Massive Upgrade Over the Previous Version, both in terms of features as well as playing strength. Over the course of 100 games played on 3 seconds + 1 second increment, the new engine was +200 elo stronger than the previous version of the engine. If playing with 4 threads, there will be a +100 elo increase.

This engine fully handles all AXF (Asian Xiangqi Federation) repetition rules such as perpetual check, perpetual chase, alternative check and kill, etc.

I approximately this engine to be around 2560+ rating. It plays slighly better thanhttps://github.com/xqbase/eleeye engine, and in testing, it beats the Elephant Eye engine on 1 second + 0.12 second increment.

Engine Options:
Hash: Sets the size of the transposition table in megabytes
Threads: Sets the number of threads used by the engine. 4 threads increases playing strength by +100. Up to 256 threads (do not use 256 threads unless you have the appropriate hardware to handle such a computation)
MultiPV: Sets the number of PV's produced by the engine per depth

The evaluation function of this engine is an Efficiently Updatable Neural Networks with Incremental Update, trained on 40000 Grandmaster Games + 20000 Synthetic Games, on around 90 Million Positions. This is a 2 Layer Neural Network (2 x (1620 x 128) -> 1).
