Dengan banyaknya engine-engine catur yang dibuat oleh para programmer, baik yang komersial maupun yang gratis, kita sebagai pemakai sangat diuntungkan. Kita bisa memilih mana engine yang baik, kuat dan sesuai dengan gaya bermain kita. Semakin banyak engine yang kita pakai, tentu semakin baik untuk perbendaharaan berlatih kita.
Engine-engine catur terus bersaing satu sama lain untuk merebut gelar terbaik. Pertarungan ini secara tidak langsung akan menaikkan gengsi dan pamor para programmernya. Engine Toga merupakan engine catur yang mengalami perkembangan yang cukup pesat. Versi terakhir (Tiga II v 1.4.1SE ratingnya sudah tembus angka psikologis yaitu 3000!). Jadi bisa dibayangkan betapa kuatnya engine Toga II ini sekarang. Jelas versi terbaru ini akan meramaikan persaingan antar engine catur kelas dunia. Keberadaan engine Toga II akan bisa mengancam engine-engine pesaingnya, jika mereka lambat dalam mengupdatenya. Saya cukup khawatir bahwa Rybka akan disalip oleh engine-engine lainnya termasuk Toga II.
Berikut saya cuplikan (sengaja saya biarkan dalam bahasa Inggris) tentang engine Toga dari situs resminya :
Toga II 1.3x4 based on Fruit is a UCI-only chess engine. This distribution comes up only with Windows executable and platform-independent source code.
Official distribution ---------------------
You can download the GNU GPL Package (incl. sources) with Toga II based on Fruit at: http://www.superchessengine.com/ or send an email to togaII@gmx.de
Version -------
Toga II 1.3x4 based on Fruit 2.1
Following changes and extensions made:
- improved history pruning - improved futility pruning - improved lazy evaluation - new evaluation features (outpost knight etc.) - MultiPV Mode
New in 1.2
- more pruning - more extensions - new settings by Dieter Eberle
New in 1.2.1
- new settings - some minor bugfixes
new in 1.3x4
- changes in eval - changes in search - Endgame bitbases by Daniel Shawul (Scorpio)
A very big thank to Daniel for sharing his great endgame bitbases and his dll.
EGBBs ----- Toga uses the Scorpio endgame bitbases upto 5 pieces.
Installation ------------ First You have to download the 5men bitbases from Leo Dijksman's WBEC site http://www.wbec-ridderkerk.nl . The egbbs are 340mb in size. Then put them anywhere in your computer. The default path is c:\egbb\ but you can change this in the uci options. The egbbdll.dll must be in the same folder as the bitbase files.
Thanks Fabien Letouzey for the great source code of the program Fruit 2.1.
Special thanks to Dieter Eberle, Karl-Heinz Söntges, Shaun Brewer for testing Beta Versions. A big thank to Dieter Eberle for his setting. Orlando Mouchel for bugfixes and new ideas. Raimund Heid for his new ideas. Wilhelm Hudetz for the Logo.
Without their help i wouldn´t be able to increase the playing strenght, compared to Fruit 2.1, by about 100 Elo.
