Preliminary results after the first round

The incoming results have been properly recorded, at last. We are now awaiting copies of five answer sheets from Kirkenes vgs. Apparently, the originals have been lost in the mail. In total, there 3420 competing this year. This is a large drop in participation form last year's 4213. We will try to learn about the causes via a questionnaire sometime early next year.

Of the 3420 participants, 2041 used the online version, while 1379 used the paper version of the competition. Surprisingly, 774 competitors (22.6%) chose to be anonymous this year. Perhaps this is due to the increased public awareness of privacy issues, triggered by GDPR.

It looks like 59 points will be neede to qualify for the second round, and 46 points to get a diploma. These numbers are higher than last year, indicating that we are succeeding in bringing the level of difficulty under control.

For you who wish to compare your own result with others': Here is a list of points and cumulative percentages. For example, those who got 39 points are among the top 49.04% of the participants.

Upcoming changes to the Abel competition

From the fall of 2018, the Norwegian Centre for Mathematics Education will take over much of the practical work associated with the competition. The biggest change is that the competition goes digital. The practical details are still being worked out. More details will appear later. See also the Norwegian version of this announcement, which is a bit more detailed.

Results from IMO 2017

In the 59th International Mathematical Olympiad (IMO) in Cluj-Napoca, Romania, Norway made 56th place among 107 competing countries. This year's winning country was USA, followed by Russia, China, Ukraina, and Thailand.

Andreas Alberg came in 147th, and Bjørnar Gullikstad Hem in 157th place, among 594 competitors, and won Bronze medals thereby. Additionally, Erik Mingjun Ma received honourable mention for his solution of Problem 1.

In the next four years, IMO will be arranged in the UK (2019), Russia (2020), USA (2021), and then in Norway (2022).

The 2018 finals

The finals were held on 7 March at NTNU in Trondheim. Andreas Alberg (Fagerborg skole) gained first place with 38 points. Bjørnar Gullikstad Hem (Nadderud vgs) and Erik Ma (Trondheim katedralskole) got second and third places, with 34 and 31 points. The prize ceremony was held at Frimurerlogen, where the minister of education and integration, Jan Tore Sanner, presented the prizes. We have a more detailed score board.

Results from round 2

Etter to runder i Abelkonkurransen har Andreas Alberg (Fagerborg skole, 185 poeng) førsteplassen, fulgt av Sigvart Brendberg (Kristen vgs Trøndelag, 175 poeng), Donny Chan (Møglestu vgs, 160 poeng) og Bjørnar Gullikstad Hem (Nadderud vgs, også 160 poeng).

Andreas Alberg (Fagerborg skole, 185 points) has taken first place after two rounds of the Abelcompetition, followed by Sigvart Brendberg (Kristen vgs Trøndelag, 175 points), Donny Chan (Møglestu vgs, 160 points), and Bjørnar Gullikstad Hem (Nadderud vgs, also 160 points).

In the second round there were 413 competitors from 135 schools. The results from the best third – 136 participants – can be found here (in Norwegian; updated 16 February). (Those who have not given permission by checking the appropriate box on the answer sheet, are listed as N.N. If you do want your name on the list after all, or if you prefer to be listed as N.N., get in touch, and we will update the list.)

At least the 20 first on the list will be invited to the finals in Trondheim. We usually invite a few more, in order to recruit for international competitions. (Exchange students without Norwegian citizenship or permanent residence in Norway do not qualify for the international competitions.) The exact number will to be invited will be decided upon very soon, after which an invitation email is sent to the finalists.

A few words regarding the problems: Clearly, we have made this problem set too difficult. That's especially unfortunate after we made such good progress with achieving a reasonable level of difficulty in the first round! We will learn from this, and do better next year. (But there should always be some difficult problems!)

We have also received a number of reactions to problem 2. That's a trick question, they say, and that is not entirely wrong. A very large number of competitors were tricked by it. Again, we should learn from this and not do it again.

Below is a list of points and cumulative percentages. For example, those who earned 120 points are among the 8.5 percent best.

185: 0.2% · 175: 0.5% · 160: 1.0% · 147: 1.2% · 146: 2.2% · 145: 2.4% · 141: 2.7% · 140: 3.1% · 135: 4.1% · 133: 4.4% · 132: 4.6% · 131: 5.1% · 130: 5.3% · 128: 5.6% · 127: 6.1% · 126: 6.5% · 125: 7.0% · 122: 7.5% · 121: 8.0% · 120: 8.5% · 117: 9.0% · 116: 9.7% · 115: 10.2% · 112: 10.7% · 111: 10.9% · 110: 12.1% · 109: 12.6% · 108: 13.1% · 107: 13.8% · 105: 14.8% · 104: 15.5% · 103: 16.5% · 102: 17.4% · 101: 17.9% · 100: 18.9% · 99: 19.1% · 98: 19.4% · 97: 20.6% · 96: 21.1% · 95: 22.8% · 94: 24.5% · 93: 25.2% · 92: 25.9% · 91: 26.4% · 90: 28.1% · 89: 29.3% · 88: 31.2% · 87: 32.2% · 86: 32.9% · 85: 34.1% · 84: 35.1% · 83: 35.4% · 82: 37.0% · 81: 38.5% · 80: 40.9% · 79: 42.1% · 78: 44.1% · 77: 46.2% · 76: 47.5% · 75: 50.8% · 74: 54.2% · 73: 56.7% · 72: 58.6% · 71: 62.0% · 70: 64.9% · 69: 65.9% · 68: 66.3% · 67: 66.6% · 66: 68.5% · 65: 71.9% · 64: 74.3% · 63: 76.5% · 62: 80.4% · 61: 84.0% · 60: 86.0% · 59: 86.7% · 58: 87.2% · 57: 88.4% · 56: 89.6% · 55: 92.5% · 54: 94.2% · 53: 95.9% · 52: 97.1% · 51: 100.0%.

Results from Round 1

The results from Round 1 have been recorded and quality checked. The list of results is now available. (The list is updated after round 2: Names and classes corrected.)

In total there were 4213 contestants from 247 schools. (That is an increase of nearly 7 % since last year, and the highest number we have had in years.) At least 51 points will be required to go on to round 2, and 38 points to receive a diploma. So it appears that we have succeeded reasonably well in reducing the level of difficulty compared to last year.

For you who wish to compare your own result with others': Here is a list of points and cumulative percentages. For example, those who got 33 points are among the top 50.06% of the participants.

NMC, EGMO, and IMO 2017

Some news items we have neglected this spring:

The 31st Nordic Mathmematical Contest (NMC 2017) was run on 3 April 2017 in the schhols. Sweden dominated the top of the results list, with the top five places. Björn Magnusson won a a single point before a shared second place. The best Norwegian score was achieved by Marius Stensrud, who got a shared sixth place. The Norwegians did quite well, taking ten out of the top 30 places.

The sixth European Girls' Mathematical Olympiad (EGMO 2017) was held in Zürich 6–12 April. Anna Lyubarskaja received a bronze medal for her 73rd place among 168 contestants, while Yuting (Samanda) Hu received honourable mention for her solution of Problem 1.

To the 58th International Mathematical Olympiad (IMO 2017) Norway sends a team consisting of

  • Andreas Alberg (Fagerborg skole)

Results from Round 1

Update: It has been discovered that the results from Nannestad vgs have not arrived. The results list and the numbers below have now been updated.

The results from Round 1 have been recorded and quality checked. The list of results is now available (updated 22 December).

In total there were 3910 contestants from 224 schools. (That is an increase of 10 % since last year, and the highest number we have had in years.) At least 43 points will be required to go on to round 2, and 31 points to receive a diploma. Corresponding numbers last year were 50 and 38, while the year before that they were 60 and 45. This shows clearly that this year's problems were much too difficult! For my own part, I can only add that I suspected this before we sent out the problems, but by then it was too late to do anything about it.

The 30th Nordic Mathematical Contest (NMC 2016) was held at the schools on 5 April 2016. There were 85 contestants altogether. Among the Norwegian participants Marius Stensrud (Ski vgs) earned a shared second place, while Weronika Wrzos-Kaminska (Nadderud vgs) achieved 11th place, and Anna Lyubarskaja came in 22nd. David Wärn from Sweden won the contest by a clear margin.

The fifth European Girls' Matehematical Olympiad (EGMO 2016) took place in Bușteni, Romania 10–16 April 2016. Norway was represented by a team of four, and received two bronze medals (Anna Lyubarskaja, Weronika Wrzos-Kaminska).

IMO 2020 in Oslo?

A group based at Department of Mathematics at the University of Oslo is working to get IMO 2020 to Norway. This is a big task, both logistically and in economic terms. We keep our fingers crossed, and wish them all luck with the application.

The host countries for the years before 2020 have already been decided.

The Abel finals 2016

This year's finals are over. Weronika Wrzos-Kaminska (Nadderud vgs) won the competition with 31 points, while Marius Stensrud (Ski vgs) captured the second place, and Bruno Kacper Mlodozeniec (Kristiansand katedralskole Gimle) came third. Roger Antonsen warmed up the audience before the prize ceremony with a lecture on The magical patterns of mathematics, after which Minister of education Torbjørn Røe Isaksen handed out diplomas and prizes to the competitors.

A partial list of results is available. The problems for the finals are available on the problems page (see the menu). The solutions will be made available later. (Update: They are available now.)

The 2016 finals

This year's finals are about to begin. The 28 best after round 2 have been invited, and all of them have accepted the invitation. We start with three days of training. The final competition is on Tuesday, 1 March, and the Minister of education, Torbjørn Røe Isaksen hands out the prizes in the evening of that day.

Results from the second round

The results from the second round are now ready. Muxuan Yan and Zezhen Xiong (Red Cross Nordic UWC) both achieved 190 points and took first and second place. Andreas Alberg (Fagerborg skole) came in third.

In the second round there were 322 participants from 129 schools. The results from the best third – 111 participants – can be found here (in Norwegian). Below is a list of points and cumulative percentages. For example, those who earned 150 points are among the 3.0 percent best.

Round 2 must have been more difficult that we though: As many as 130 participants got only two right answers or less, and 55 of them managed none at all. This could be demotivating, which is against our purpose (though there should always be some difficult problems). We will try to adjust the level of difficulty doen a bit next year.

Below is a list of points and cumulative percentages. For example, those who earned 150 points are among the 2.5 percent best.

190: 0.6% · 162: 0.9% · 160: 1.3% · 157: 1.6% · 153: 1.9% · 152: 2.2% · 150: 2.5% · 146: 2.8% · 145: 3.1% · 142: 3.4% · 141: 3.8% · 133: 4.1% · 129: 4.4% · 128: 5.3% · 126: 5.6% · 124: 6.0% · 123: 6.3% · 122: 6.6% · 121: 7.2% · 120: 8.2% · 119: 8.5% · 118: 8.8% · 115: 9.7% · 114: 10.7% · 112: 11.0% · 111: 11.6% · 110: 12.5% · 106: 12.9% · 105: 14.1% · 104: 15.4% · 103: 16.3% · 102: 17.2% · 101: 17.6% · 100: 19.7% · 99: 20.1% · 98: 20.4% · 97: 20.7% · 96: 21.0% · 95: 22.3% · 94: 23.5% · 93: 23.8% · 92: 24.8% · 91: 26.3% · 90: 28.2% · 89: 29.2% · 88: 29.8% · 87: 30.7% · 86: 32.0% · 85: 34.8% · 84: 36.7% · 83: 37.3% · 82: 39.2% · 81: 41.1% · 80: 44.2% · 79: 44.5% · 78: 45.1% · 77: 45.8% · 76: 46.4% · 75: 49.8% · 74: 51.7% · 73: 55.5% · 72: 56.4% · 71: 59.2% · 70: 65.2% · 68: 66.1% · 67: 67.7% · 66: 68.7% · 65: 72.4% · 64: 73.7% · 63: 74.0% · 62: 75.5% · 61: 78.7% · 60: 86.2% · 59: 86.8% · 58: 87.1% · 56: 88.7% · 55: 90.9% · 54: 93.7% · 53: 94.0% · 52: 94.7% · 51: 95.0% · 50: 100.0%.

Round 2 is over

Problems and a solution (Norwegian only) may be found on the problem page. I am sorry about the delay, which is due to illness.

Since the finals are early this year, we have some extra pressure to finish the results list soon. Hopefully we can have it ready by the end of the month.

And while on the subject of results lists: There have been some request for the results list after round 1. We have in the past published the top third or so. However, we have learned that this requires permission from each participant. From round 2 we have sought such permission.

Results from Round 1

The results from Round 1 have been recorded and quality checked.

In total there were 3547 contestants from 219 schools. At least 50 points will be required to go on to round 2, and 38 points to receive a diploma. Corresponding numbers last year were 60 and 45, so it is clear that the problems this year were quite a bit more difficult than the ones last year. This year's numbers are more like those from two years ago, when we concluded that the problems were too difficult. It is hard to avoid drawing the same conclusion this year.

As soon as the diplomas arrive from the printer, Monday we think, they will be sent out along with the results for each school.

For you who wish to compare your own result with others': Here is a list of points and cumulative percentages. For example, those who got 34 points are among the top 50.52% of the participants.

100: 0.03% · 96: 0.06% · 92: 0.11% · 90: 0.17% · 83: 0.23% · 80: 0.25% · 79: 0.28% · 78: 0.31% · 77: 0.34% · 76: 0.37% · 75: 0.39% · 74: 0.42% · 72: 0.51% · 71: 0.59% · 70: 0.79% · 69: 0.85% · 68: 0.93% · 67: 0.96% · 66: 0.99% · 65: 1.30% · 64: 1.52% · 63: 1.72% · 62: 1.83% · 61: 2.20% · 60: 2.82% · 59: 3.04% · 58: 3.33% · 57: 3.61% · 56: 4.06% · 55: 5.27% · 54: 6.17% · 53: 6.57% · 52: 7.22% · 51: 7.92% · 50: 10.01% · 49: 10.94% · 48: 12.18% · 47: 13.48% · 46: 14.89% · 45: 17.71% · 44: 19.17% · 43: 21.14% · 42: 23.17% · 41: 25.46% · 40: 30.50% · 39: 33.18% · 38: 35.61% · 37: 38.40% · 36: 41.42% · 35: 47.22% · 34: 50.52% · 33: 53.62% · 32: 56.50% · 31: 60.05% · 30: 66.76% · 29: 69.69% · 28: 72.20% · 27: 74.96% · 26: 77.11% · 25: 82.18% · 24: 84.55% · 23: 86.33% · 22: 87.96% · 21: 89.34% · 20: 93.77%.

After round 1

Most of the answer sheets have now arrived. There are about 3531 participants from 218 schools. Registering all this data will take time, and I expect we will be a week or two into December before we know the distribution of scores and can tell what is required to receive a diploma or move on to round two. We will inform here when the numbers are ready.

List of results after round 1

We have prepared a list of results after round 1. The list is shortened; only the best 50 percent (approximately) are included. Diplomas for the top third (those with at least 45 points) have been sent to the schools along with a complete results list. Their fate is now up to higher powers (the postal service). The problems for round 2 will be sent out in January.

PS. There was a misprint in the results list: The first paragraph stated wrongly that those with at least 50 points are qualified for the second round. The correct number is 60. The same misprint is in the complete results list sent to the schools. The summary statistics per school were also based on the wrong cutoffs. A new results list has been posted.

About problem 10, and preliminary results from Round 1

Problem 10 i this year's Round 1 has led to som discussion, and we have received a number of queries about it. This was a combinatorics problem which could be misinterpreted, as it turned out. We have made available an explanation (in Norwegian) of the problem, our intended interpretation, and an analysis of more or less reasonable misinterpretations.

We have now registered all incoming answers, and finished the quality assurance work. There were 3396 participants in Round one. All who achieved 60 points or more qualify for Round two, while all with at least 45 points get a diploma. (Last year the cutoffs were 51 and 38 points, which indicates that we have succeeded in making the problems easier.)

For you who wish to compare your own result with others': Here is a list of points and cumulative percentages. For example, those who got 38 points are among the top 49.47% of the participants.

A preview of results after round 1

About 3400 answers to round 1 have been received. We are well under way with the recording of the results; a bit over 2350 answers have been registered so far. If the current trend holds for the final 1000 answers, all competitors with at least 60 points will be eligible to take part in round 2, while all with at least 46 points will be awarded a diploma.

Apart from that, the text of problem 10 has led to quite a bit of discussion, and some feedback from competitors and teachers alike. We have to agree that the problem could have been better worded, and are working on a more thorough description of the issues with this problem. This will be posted to the web when it is ready.

Misprints in the English version

Three misprints has been discovered in the English version of the problems. The number 29 in problem 8 should be 20 (as it is in the Norwegian versions). Less seriously, in problem 20, end of the third line, the word “market” should be “marked”. And the date on the front page was wrong too: It should be 6 November.

If you are a teacher, please make these corrections. If you are a competitor, please alert your teacher so he/she can make the necessary corrections.

We are deeply sorry about this misprint. The above notice was prominently displayed on the web page before the competition – it seemed the best thing we could do to try to remedy the situation.

List of results after round 1

We have prepared a list of results after round 1. The list is shortened; only the approximately 50 percent best are included.

By Harald Hanche-Olsen, 18.12.2013

Results from the first round

In the first round there were 3473 participants from 213 schools. Those who got 51 points or more are qualified for the second round, while those who got 38 points or more receive a diploma.

All data is now registered and proofread, and the data below has been updated.

It is now painfully obviius that will not be able to send diplomas and results lists to the schools in time for the end-of-term celebrations. We are really sorry about this, and will try to do better in the coming years. A message will appear here once the results have been shipped.

For you who wish to compare your own result with others': Here is a list of points and cumulative percentages. For example, those who got 33 points are among the top 49,73% of the participants.

Registering and participation in the Abel Competition

Participation in the Abel Competition is arranged by the schools. Individual pupils who wish to take part, must arrange this with a mathematics teacher at their own school or another school nearby.

High schools which have participated in the later years, get the problems sent automatically. They do not need to do anything special in order to register but if the school's address has changed recently, we would like to know. Use our email address (see our contact page) for registration, address changes, and other inquiries.

Lower schools (ungdommsskoler) who wish to participate, must register every year. If you are a pupil in such a school who wishes to participate, you must either arrange this via your own school, or a high school nearby. Your mathematics teacher should be able to help you with this.

Results from the first round

In the first round there were 3433 participants from 226 schools. Those who got 56 points or more are qualified for the second round, while those who got 41 points or more receive a diploma.

Please note: In the results folder that was sent to the school yesterday, there is an unfortunate mistake: Starting on page two is a list of participants “qualified for the second round”, sorted by descending points. Unfortunately, the list continuous all the down to the limit for receiving a diploma, i.e., 41 points, rather than stopping at 56 points as it should. We regret this error, and hope it does not lead to too much confusion. Many thanks to Kvaløya vgs, who made us aware of the problem.

For you who wish to compare your own result with others': Here is a list of points and cumulative percentages. For example, those who got 35 points are among the top 49,72% of the participants.

A quick update

We got started late with registering the results from the first round, for reasons we will not bother you with. But by now, 2360 of 3410 results have been registered. If the last thousand aren't very different, it appears that the cut-off for making it into the second round will be around 55 points. These numbers indicate that we have succeeded in making the problems somewhat easier than they have been the past few years.

We hope to be able to send out the final results list, with diplomas and the problems for the second round, to the schools no later than 11 December.
