There will be 3 freestyle groups, 1 fastgame group, 1 standard group, and 1 renju group in Tournament 2017.
For Freestyle 2 and 3, the top 4 AIs will move up to the next group. If the top k (k>4) places were all taken by new (or updated) AIs in a group, then all these k AIs would advance to the next group.

In the past year, we were informed that HGarden was plagiarized from Carbon Gomoku. Concretely, we were noticed that the string "AICarbon" could be found by opening the .exe file of HGarden with a text editor. Further in-depth analysis demonstrated that the logic of HGarden is quite similar to that of Carbon. Based on this information, considering that Carbon Gomoku has been an open-source AI since 2002, it's very likely HGarden is based on Carbon. However, on the one hand, the author of HGarden does not mention anything about Carbon Gomoku in HGarden, and on the other hand, the authorship requirement of Gomocup requires that one person should submit at most one AI to the tournament as the first author, and Carbon Gomoku joined Gomocup from 2016. Therefore, we think it would be inappropriate for HGarden to remain in Gomocup.
Before making the above decision, we had already contacted the author of HGarden to ask if he thought any part of the accusation was not true. However, we did not receive any response.
In Gomocup 2016, Nabamoku caused a problem -- we found that computers were quite stuck when running Nabamoku, even if we restrict it to run on one core by setting the CPU affinity. Because of this issue, to ensure the other AIs were not influenced, we had to restart several games last year. To avoid the same problem, we decide to remove Nabamoku from the tournaments starting from this year.
