Black Marlin - UCI engine, Author: Doruk SEKERCIOGLU
Rating CEDR=3515
v.9.0:
Black Marlin 9.0 gains ~90 Elo over Black Marlin 8.0 at long time controls and makes a few significant changes to the engine behavior.
The time management algorithm has been entirely rewritten, fixing the problem where Black Marlin could think up to 80% of its remaining time on a single move.
Black Marlin 9.0 is the first release to target improvement in longer time controls. The search algorithm has been tuned for long time control performance at over 500000 games. The time management has also been tuned with genetic algorithms to optimize performance for long time controls.
Black Marlin 9.0 benefits from significant improvements in the Neural Network Evaluation including a larger dataset of 3.5 billion chess positions. This release also fixes the issue where Black Marlin would rate winning endgames close to drawn.
Despite being slower due to the larger neural network, Black Marlin 9.0 comes with significant performance improvements that users will especially benefit from with larger Hash sizes.
