This is the content of the readme.txt file: Name: SOS for Arena Programmer: Rudolf Huber Country: Germany Version: 4 ELO: ~ 2.650 Playing Styl: Strategy "SOS is an amateur program which was started in 1993 and has since then competed in a number of tournaments. The newest version runs on multiprocessor systems with a parallelized version of mtd(f) as its minimax search algorithm. SOS used to be a realativley fast searcher and relied on outsearching the opponent. This has changed now and more knowledge and special cases have been implemented which slow it down. Little effort is spent on the opening book. It plays a very broad range of openings. However it learns to avoid unsuccessful lines and tries not to repeat lost games. It uses publictly available endgame databases." Protocol: UCI (setup version) Opening book: Main book included in setup. SOS supported: Nalimov tablebases (endgame databases): ftp://ftp.cis.uab.edu/pub/hyatt/TB/ (three and four pieces = 31.05 Mb) Offical results: ---------------- 1993, 12th WMCCC Munich 4/9 points, ranking 20 of 28 1997, 15th WMCCC Paris 5/11 points, ranking 26 of 34 1999, 16th WMCCC Paderborn 2.5/7 points, ranking 24 of 30 2000, 17th WMCCC London, Amateur World Champion 5.5/9 points, ranking 6 of 14 2001, 18th WMCCC Maastricht 5/9 points, ranking 11 of 18 1995, 08th WCCC HongKong 2/5 points, ranking 15 of 24 2002, 10th WCCC Maastricht 4.5/9 points, ranking 9 of 18 1994, 04th IPCCC Paderborn 5/7 points, ranking 2 of 18 1997, 06th IPCCC Paderborn 4.5/7 points, ranking 4 of 16 1998, 07th IPCCC Paderborn 3/7 points, ranking 11 of 16 1999, 08th IPCCC Paderborn 4/7 points, ranking 7 of 14 2000, 09th IPCCC Paderborn 3.5/7 points, ranking 7 of 16 2001, 10th IPCCC Paderborn 5/9 points, ranking 5 of 18 2002, 11th IPCCC Paderborn 3.5/7 points, ranking 9 of 16 2003, 12th IPCCC Paderborn 4.5/7 points, ranking 4 of 14 2001, 1st Int.
