A couple of days ago, the first round of the annual Russian AI Cup championship ended . And according to its results, today we have prepared all kinds of statistics for you. By the time the first round began, more than 1,500 participants had uploaded their strategies to the system. Of these, the 900 best in terms of ranking in the Sandbox fought for the right to participate in the second round of the championship. The competition was three people in place, so everyone had enough adrenaline.

The first round consisted of two parts, each of 12 hours of continuous calculation. There was a daily break between the parts, during which the participants had the opportunity to refine their strategies. On average, contestants participated in more than 100 games during each part of the first round. It is curious that in the second part we managed to conduct slightly fewer fights, which is probably due to the complication of strategies and the work on errors during the daily break.

The results of the games on the site were not updated immediately, but with a 15-minute delay. This was done specifically to create more intrigue, in these 15 minutes many of the participants were able to feel like Anatoly Tarasov, empathizing with his team. And how much adrenaline spilled out during the viewing of the games themselves!

Regarding general statistics, we want to draw your attention to a few interesting points. For example, it is interesting that the results of the first round are often very different from the ratings received by the participants in the Sandbox. Apparently, this is due to the peculiarity of the selection of opponents. Indeed, in the Sandbox, participants fight with peers of equal value, and during the first round, the selection of rivals was random.

So, in the first round, the mysterious participant recar won, leaving very little information about himself in the profile. The winner of the 2012 Championship Nikolay “Mr.Smile” Vabishchevich took a worthy sixth place.
