*) In comparison with a 486DX/33 PC (rough estimate)



In the IOS Open IV (1995) Logistello lost a decisive game to ECLIPSE and can blame its operator for this who called it with an incomplete book in which several paths were not evaluated. Anyway, the result of an 12 game match held two weeks later was 7-5-0=79% in favour of Logistello.



On May 16th, 1996 a six-game match was scheduled between the sequential version of Keyano and Logistello. It was mutually aborted after three games and a score of 3-0 in favour of LOG. Keyano's evaluation function and its book need improvement ...



July '97: Tetsuya Nakajima vs. Logistello: 0-2



August '97: Takeshi Murakami vs. Logistello: 0-6



In the "Princeton I" computer Othello tournament played on IOS in October '97, Logistello won 22 games in a row.

January '98: Logistello retires after four years of successful tournament play. After winning all of the five major annual machine Othello tournaments, including the perfect score achieved in the "Princeton I" event, the time has come to move on and to hand over the torch to promising newer programs. Machine Othello has experienced a boost during the last five years due to the competition and open discussions between authors of the best programs. I hope that this tradition will continue in order to increase the programs' playing strength even further.
