Allegations against another Chess Engine

Allegations against another Chess Engine
The LOOP Program
By David Levy

The International Computer Games Association (ICGA) has received a formal complaint from Fabien Letouzey, the programmer of FRUIT, regarding the program LOOP. The allegation is that LOOP, which has participated in the World Computer Chess Championship, uses code derived from FRUIT, which placed second at the 2005 World Computer Chess Championship in Reykjavik.

LOOP was developed by Dr Fritz Reul. The ICGA has attempted to contact Dr Reul in order to give him the opportunity of commenting on the allegation prior to the ICGA conducting a technical investigation into LOOP, but it appears to us that Dr Reul does not wish to be found. The email address that had previously been used by Dr Reul is no longer active, so on behalf of the ICGA I sent him an email via a friend of his who indicated that he would pass my email on to Dr Reul, did not respond to that email.

The ICGA is now planning to conduct an investigation into LOOP in order to examine the allegation about the use of code derived from FRUIT and once again invites Dr Reul, to contact the ICGA with his comments on the matter.

If Dr Reul does make contact with the ICGA he will be given every opportunity to defend himself against the allegations, including an invitation for him to comment on any evidence that the ICGA might consider during the investigation process.

If, by March 31st 2012, Dr Reul does not make contact with the ICGA in order to co-operate over this matter, the ICGA will commence its investigation “in absentia”.
