Artemis Chess 1.1.0 - chess engine and GUI

-


v. 1.1.0:
The Killer Moves table now updates every time a cutoff occurs, instead of keeping the first 2 values.

This generally means that deeper moves will replace the old ones.

Also, instead of clearing the table after each search, it now gets shifted by 2 plies, keeping the moves found in previous searches. This change increased the number of alpha-beta cutoffs caused by killer moves.

The Null Move heuristic received a small tweak that greatly improved it: previously, it was limitied to depth>3.

Removing this limit vastly increased the number of alpha-beta cutoffs it achieved. This in turn yielded an increase to NPS, without apparent negative effects.

The engine now prints stats like NPS, alpha-beta cutoffs, etc., which helped discover the improvements in this version.

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...
