Chess engine: Cadie 1.7

-


Cadie - UCI Engine
Author: Martin Wyngaarden  Rating CEDR=3007

v.1.7:
This release includes many bug fixes, improvements, and search refinements. In self-play, Cadie 1.7 is ~105 Elo stronger than Cadie 1.5 at the 120"+1" time control. Hopefully, this will translate to at least 80 Elo in the rating lists.

Most of the code changes are refactoring. Elo gains come mainly from a re-tuned evaluation and the speedup from converting from mailbox to the bitboard board representation. The bitboard implementation is not unique, and is being reused with permission from Thomas Jahn (https://github.com/lithander/Leorik)

Windows executables are attached. These have only been tested on Windows 10.

Cadie_1.7D.exe: Dynamic linkage
Cadie_1.7T.exe: Static linkage

Jim Ablett's build is easily the most performant.

We already have the new Fritz 20 program - what does it look like and how does it work?

The purchase process for the download version on the ChessBase website took only 5 minutes. Downloading the files from the cloud was even quicker. The installation itself, which involved five large files, took maybe 7 minutes, including restarting the system and entering the serial number I received upon purchase. The start image for Fritz 20 has a strange mosaic of colors; perhaps I'll get used to it. As you can see in the second screenshot, the program interface hasn't changed much; only the icons are different (we've been using Fritz 17 until now). It looks nice, but it's no major revolution. The next two screenshots show engine management and the installation of the UCI chess engine (here, Cataphract 1.1). As you can see, there are no changes. Screenshot no. 5 shows the analysis of some position by Fritz 20 engines. The changes are minimal - it is still very legible. Finally, on screen 6 we have the engine tournament table generated by Fritz 20 . I think it is sti...
