Chess engine: Lambergar 0.4.1 (Windows and Linux)

on

 


Lambergar - UCI chess engine  Rating CEDR=2624
Lambergar is a chess engine developed in the Zig programming language. 

The name "Lambergar" is a nod to the Slovenian folk romance, Pegam and Lambergar, which recounts the epic struggle between Jan Vitovec and Kriลกtof Lambergar (Lamberg). This narrative of fortitude and rivalry provided a fitting namesake for this chess engine.

v.0.4.0:
This release includes two bug fixes:
Excessive Memory Usage: We resolved an issue with excessive memory usage. The problem originated from the use of an incorrect memory allocator. Previously, we used the Arena memory allocator, which, according to a discussion on Ziggit, does not release memory. We have now switched to using the c_allocator directly.

Engine Unresponsiveness: We fixed an issue where the engine would get stuck in search mode and not respond to commands from the interface. This was due to the use of a single thread, and interfacing was only possible once the search had finished. We have now resolved this by using a separate thread for the search routine. This improvement also lays the groundwork for implementing a multi-threaded search in the future.

Please note that these changes do not improve the engine's strength.
