Difficult to compare, because they don't play the same game. :-) Scatha plays hexagonal chess, while Glaurung plays normal chess. Scatha was written first (some time during the summer last year, IIRC), and Glaurung started as a straightforward translation of Scatha to normal chess. Since then, the two programs have been developed in parallell; whenever I add some new feature or improvement to Glaurung, I add the same code to Scatha. The source code in the two programs is still 95% the same. By making a few arrays a bit bigger, I could probably have merged both programs to a single executable. At the moment, Scatha 0.2.10 is a bit more up to date than the latest public version of Glaurung, but the differences are not very exciting. This autumn I have mostly worked on the GUI; the engine code hasn't changed much. The only really important difference between Scatha 0.2.10 and Glaurung Mainz is the hash table bug mentioned elsewhere in this thread. If it turns out that fixing this bug leads to a big improvement in strength, I will probably release a Glaurung 0.2.10 some time soon. The names of my programs are probably rather confusing at the moment. The GUI is called "Scatha", even though it contains *both* of the engines (Scatha and Glaurung). This has historical reasons -- originally the GUI only supported hexagonal chess, and I intended to write a separate GUI for Glaurung later. Eventually I decided that it would be easier to add rectangular chess support to the Scatha GUI instead. Perhaps I should change the name of the GUI to something else in order to avoid the confusion. I should also write some kind of Glaurung and Scatha FAQ. Tord
