Fischer-Schneider

the first German chess program developed since 1965 by two math students at [|University of Stuttgart], Hans-Jochen Schneider and Kurt Fischer. Initially written in a assembly language dubbed TEXAS (Telefunken Externcode Assembler) for a [|Telefunken] TR-4 mainframe computer, it was later ported to run on a IBM System 360. Fischer-Schneider participated at the First GI Computer Chess Tournament 1975 with a 50% score, and in 1973 gained some publicity when it played and lost to [|Paul Keres] and [|Boris Spassky] during their visit at the [|GMD-Forschungszentrum], [|Schloss Birlinghoven] in [|Sankt Augustin]. || toc =Description= Fischer-Schneider was a for that time typical Shannon Type B program using "plausible" move generation. The move selection was applied through recursive eliminiation of moves compromising material safety. The evaluation was quite sophisticated, considering material, attacked and defended pieces for a swap-off algorithm, mobility, square control and king-piece tropism. Special feature was the ability of the program to recognize draws by repetition, already maintaining and traversing a list of positions until the last irreversible move.
