New version chess engine: Serendipity 1.0 (java)

Serendipity, an UCI chess engine written in Java.

Author - Xu-shawn

v.1.0:

This release marks the one year anniversary of the Serendipity project. Compared to v0.4.1, this release introduces the following new features:

Larger evaluation network with SIMD-accelerated inference through Java's Vector API. Due to this dependency, Serendipity will longer support JRE versions lower than 17.

Improved time management

3x more compact transposition table

Various search improvements

To run Serendipity, install the Java Runtime Environment (version >= 17), and make sure that the JRE is under system path. Then, run the program either through directly running the exe or through the command java --add-modules jdk.incubator.vector -jar Serendipity-1.0.0.jar.
