ZCT, my old chess program
License: GNU General Public License v3.0
You are now looking at the first release of the chess-playing software project called ZCT (which stands for Zach's Chess Test). This piece of software was written by Zach Wegner, starting on June 1, 2005. STANDARD USE This program is intended for use on POSIX operating systems as well as Windows. It is a standard "console" application that does not make use of any graphical user interface. It can be used stand-alone, or through an interface using either the XBoard Engine Communication Protocol or the Universal Chess Interface. It is recommended to be used in either "console" mode or through the XBoard protocol, as UCI is not fully compatible with some of ZCT's basic design philosophies. UCI support is intended only as a last-resort option, and to be compatible with as many interfaces as possible. ZCT is a "monolithic" chess program, a la Crafty, that has many features in console mode and thus does not rely on a GUI for functions such as PGN and EPD support, an opening book, or time controls. ZCT also supports multiple processors, but must be compiled with the support in. Try 'make "CFLAGS=-DSMP -DMAX_CPUS=n"', where n is the number of processors your machine has. CODE ZCT is a rather simple program that has a small evaluation and a simple but efficient search. It's primary claim to fame is the open source implementation of DTS (Dynamic Tree Splitting), which, to my knowledge, has only been successfully implemented by four teams before: Cray Blitz (Bob Hyatt et al.), Diep (Vincent Diepeveen), Zappa (Anthony Cozzie), and MessChess (Mridul Muralidharan). The intent was to write clean, bug free code. The code is pure, modern C that I hope is found to be well written and easy to understand. ZCT is also heavily commented. If you don't understand something, drop me a line and I'll clean it up/comment it more. RELEASE This software is open source, and released with a license (COPYING.txt in the main directory). Please read this license before you use, modify, or look at anything else in the distribution! These components should be included in the distribution: README.txt--This file... COPYING.txt--The licensing information for using this software CHANGES.txt--The version-by-version history of ZCT, dating back further than you would like to know. Source files--A bunch of .c and .h files, as well as a Makefile zct.png--The standard logo for ZCT, 100x50 pixels. book.zbk--A standard opening book in ZCT's native format ZCT.ini--A standard configuration file Additionally, the distribution may contain one or more executable files, named 'zct' or 'zct.exe'. ACKNOWLEDGEMENTS This software has been enriched due to the contribution of many individuals. Among them are: Kenny Dail--hardware, beta testing, bug fixing, book work, evaluation advice Fonzy Bluemers--Beta testing, bug fixing, tweaking, eval advice, testing, godliness Teemu Pudas--Bug fixes, help in releasing, more bugfixes Swaminathan Natarajan--Tournament running, lots of eval advice Wael Deeb--Opening Book Jim Ablett--Binaries, bug fixing Dann Corbit--Bug fixes Tony Thomas, Harun Taner, Olivier Deville, Patrick Buchmann, probably others--Tournament running Claude Shannon, Alan Turing, Donald E. Knuth, Ronald W. Moore, Frans Morsch, David Slate, and more--Standard chess and tree-search theory Tom Kerrigan--TSCP helped me learn about how to write a chess program Robert Hyatt--bitboards and SMP, Crafty was also responsible for much of my development in computer chess, being the first complex engine that I saw the source to Tord Romstad--Philosophy, ideas (LMR/null-move trick) Anthony Cozzie--Philosophy, idea for print function Steffan Westcott--Kogge-Stone and subset algorithms Vincent Diepeveen, Fabien Letouzy, H.G. Muller, Gerd Isenberg, and countless other chess engine authors, beta testers, tournament managers, and fans--For general philosohpy, ideas, encouragement, advancements, and making this little waste of time we call computer chess so interesting... Additionally, the following people have supplied working code that is used in ZCT, usually in a modified form: Teemu Pudas--Windows SMP compatibility Vincent Diepeveen/Agner Fog--random number generator Gerd Isenberg--last_square() Matt Taylor--first_square() Someone else somewhere--pop_count() Robert Hyatt--input_available() Bob/Someone writing for the Linux Kernel--asm LOCK(), bitscans, and popcount on x86
