Gomocup 2014, The 15th tournament (April the 10-13th, 2014)

The Gomocup 2014 took place on April the 10th-13th. All the games were run on one computer Dell Inspiron SE-7720, Windows 8.1 x64 Intel Core i7 (Ivy Bridge) 3630QM(2.4/3.4GHz), 8GB RAM. Furthermore the piskvork server was set up to the computer in datacentre with public IP and connected to the backhaul network. The Gomocup online was redesigned with the current edge technologies like HTML5 canvas and websockets to bring real time tournament gomoku boards. On the other side the each piskvork client send moves via websockets to piskvork server. this solution was much more better, because it does not need to instantiate new connection for every move.

Openings for gomocup 2014 were again choosen by Alexander Bogatirev, gomoku player, manager of Team Russia online, member of Gomoku Committee RIF and can be found here. Thanks to Alexander.

Several old AI ws removed from Gomocup tournament, because dos programs are no more compatible with windows 8. The following incompatible AI were removed:

  • Trunkat
  • AI1000
  • Leonardo
  • Brutefor
  • Curnpis

There were technical difficulties like every year. this time it was caused by entirelly new system, but all bugs have been fixed during the tournament. Some reported, that they cannot see the online tournament even with latest HTML5 browser. This is caused, because some proxy servers doesn’t support websockets.

Standard gomoku tournament is played on board of size 15×15 fileds and exactly five stones in row wins. The openings are adjusted compare to the freestyle gomoku.

There was a new AI Zetor supporting standard gomoku. I have analyzed again AI Valkyrie and the decision has made, that it suport the standard gomoku game.

The results were different then last year. The tournament was very tight. Both Tito and Yixin has the same number of points, same ration and the match beteen them was 3:3. In such case a time per turn determines. That is why Tito became the winner in standard gomoku. Tito’s time per move was 8.9 s, while Yixin’s time per move was 12s.

The winner of standard group was Tito written by Andrej Tokarjev, the second was Yixin by Kai Sun and the third was Hewer written by Tomas Kubes.

The AI in the Fast Game were order according to Gomocup 2012 results, so the strongest AI matched in the end.

The FastGame was not tight as the last Year. New new version of Yixin quickly took control over the tournament and finally win the tournament. Congratulation to the Yixin and the author Kai Sun from China. The second was Goro and the third was Hewer. All five top position was occupied by new AI’s made in 2014.
