Since you’re here...

... we have a small favour to ask. More people, like you, are reading and supporting our blog: "Chess Engines Diary". And unlike many other sites and blogs, we made the choice to keep our articles open for all, regardless of where they live or what they can afford to pay.

We hope you will consider supporting us today. We need your support to continue to exist, because good entries are more and more work time. Every reader contribution, however big or small, is so valuable. Support "Chess Engines Diary" even a small amount– and it only takes a minute. Thank you.

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.
