AW: Zep Tepi, die erste Zeit der Computerschach Götter
 Zitat von Tibono
Hi,
thanks for the idea, Thorsten. I easily found the program itself (deep_scan.dsk) and an emulator (SimCoupe.exe). Loading the disk into drive 1 autostarts the chess program; yet it looks like only two commands are valid (apart from moves input): new (for a new game) and stop (to quit the program). There is no direct input to change the default thinking time (180 secs). The way I succeeded: - stop to exit the program - input: 15 LET time=x -----> where x is the wanted thinking time in seconds - run This inserts a new basic line that overwrites the time value previously set in line 10: Code:
10 PEN 7: LET ls=0: LET time=180: REM CPU MOVE time IN seconds Hope this helps, Eric Depending on the syntax of the basic it looks maybe different there. My tournament is all in 40/120 so this is ok for me. There are even interesting games on youtube with deep scan.

AW: Zep Tepi, die erste Zeit der Computerschach Götter
there is a read.me for Deep Scan:
Zitieren:
Unfinished chess program, attached as mentioned below is an early version of the engine from Chris Pile and graphics supplied by Gordon Wallis.
From Chris Pile Started a chess program back in 1999 - then got 'demoted' to writing games for the Gameboy Color, so the chess thingy got shelved. Gordon Wallis did some fantastic graphics - which, sadly, never saw the light of day. The engine is playable - and is time based, rather than ply depth. So one can choose the engine's thinking time for its moves. I knocked up a very rudimentary interface (mostly in BASIC) to test it against various other chess programs and a few hardware chess computers I owned. It puts up a reasonable fight - but will blunder moves occasionally. I wasn't completely happy with its performance. Picking it up again probably won't happen. It would be a rewrite if I decided to. More from Chris Pile Further to Howard Price's request to see the chess thingy "...in any form", as posted in the 'started and never finished' thread, I've dug out the very last (latest?) test version - built from a source almost a quarter of a century old! Needless to say, looking at the source it makes very little sense after all this time. It really was just a dog's dinner of a prototype/proof-of-concept. If I were to pick this up again (highly unlikely) I would start with a complete rewrite. Anyway, booting the disk will present you with a very simple chess board (just ASCII) with the pieces represented by their alpha equivalent (Q=Queen, Etc. Knights shown as 'N' or 'n')... Lower case = Black pieces; Upper = White. This test version only allows you to play as White - so you enter the first move. Moves are entered in standard algebraic notation, with nothing between the 'from' and 'to' squares: c2c4... b1c3... Etc. Lower case too. Castling is achieved by entering the 'from' and 'to' squares and not 'O-O' as some chess programs. Same with 'en passant' captures - just enter the 'from' and 'to' squares - in the case of 'en passant' the 'to' square will be empty, but the engine will know which pawn to capture. Entering 'new' (without the quotes) will start a new game; and entering 'stop' will bail out to BASIC. The BASIC interface to the engine has very few safeguards, is very clunky and certainly not an exercise in efficient BASIC programming! It was never intended for public consumption! The 'SCORE' line on the display is a measure of how well (or not!) the engine thinks it's doing. Positive scores up to 10000 (checkmate) and it thinks it is winning. Negative scores and its opponent (you or another chess engine) is winning. The engine will announce 'Mate in X' and 'Checkmate' from its perspective. However, only 'Mate in X' will be announced from your perspective. If you checkmate the engine it will still attempt to make another move. And will be stuck in a perpetual state of 'not knowing what to do!'. So, if you see the SCORE display anything over -9000 then is a pretty fair bet you (or the other chess engine) has won. In which case entering 'new' will restart. The first line of the BASIC contains the variable 'time'... This controls how many seconds the engine has to think about each move. Currently set to 180 seconds. The maximum is 1310 seconds. Basically 65536/50. So, around 20(ish) minutes per move. However, due to the way the search tree exponentially explodes the deeper it goes; beyond around 10 minutes per move doesn't really gain much extra depth - until there are very few pieces left. The old SAM just doesn't have the horsepower! The engine currently doesn't recognise stalemate or draws by repetition. So, when playing against another similarly matched engine you may find both simply blundering along in a perpetual state of check. Deep Scan will blunder moves quite often. The current board evaluation logic is flawed, and plays quite a weak game. The engine is a NEGAMAX variant of a standard Alpha/Beta minimax tree searcher; with a simple history heuristic, a narrowing/widening 'aspiration window' along the main search line and dynamic 'piece square' tables. Plans were to add hashing, a simple opening book and also some compressed endgame references. There it is - Deep Scan... The SAM chess proggy that never was!

Zug einen Läufer von c8 nach d7 obwohl er den Läufer schon im 17. Zug von C8 nach e6 gezogen hatte. Siehe letztes Bild. Da hatte ich mir gedacht: ok. gibst du die Stellung ein im 19... und lässt schwarz (Sargon) dann eben in der korrekten Stellung rechnen. Dann aber kam ein obskurer Läuferzug der denselben einstellt und danach taucht auch nach Stellungseingabe der Phantomläufer wieder auf. D.h. das Programm spielt 2x illegal. D.h. ich kann das Programm leider nicht ins Turnier setzen.

Jetzt bin ich schon irritiert. Wenn das Programm solche Verhaltensweisen zeigt ist sicherlich was gänzlich falsch.
Schade. Was sagt ihr denn dazu. Sargon 1 raus und anderes Programm rein ? Wie aus dem nichts taucht der schwarze Läufer auf c8 auf und klont sich erneut in die Partie.

So sei es dann. Schade.
Die andere Partie zwischen Psi Chess und Deep Scan war sehr spannend. Auch wenn die sich drehte. Eine lange Zeit lang stand Psi chess besser. Und dann allerdings drehte sich das Blatt und Deep Scan konnte das noch nach Hause fahren. Also erster Sieg von Deep Scan !!

AW: Zep Tepi, die erste Zeit der Computerschach Götter
ok, Sargon I raus und MSX Chess V1.1 rein.
Das Programm ist von Adam Waring. https://www.generation-msx.nl/softwa.../release/3631/ Es ist wohl sehr spät herausgekommen (1986) aber da wir noch keinen MSX Homecomputer drin haben, passt das schon. Die erste Partie ist wie vordem gegen Senator Chess von SciSys. Etwas aufpassen muss ich weil das Feld A1 hell ist. D.h. genau umgekehrt wie ein normales Brett. Da muss ich aufpassen nicht verkehrt zu ziehen. Immerhin kann man eine durchschnittliche Rechenzeit eingeben. Soweit ich das sehe hat Adam auch eine Rezension über Colossus Chess geschrieben : https://www.everygamegoing.com/larti...4-0-000/26921/
