Igel is a free UCI chess engine forked from GreKo 2018.01.
It is not a complete chess program and requires a UCI compatible GUI software in order to be used.
Igel is published under an open source license.
- NNUE as a main evaluation function using Dietrich Kappe’s NiNu network file.
- Igel Generation Network (IGN) – the developer’s own class of networks. They comply with the following requirements:
- Source of network data: evaluation, search, pv line is generated solely using Igel chess engine. As a starting point Igel 2.6.0 is choosen as this was the last version of Igel featuring HCE (Hand Crafted Evaluation).
- Both data and validation data generation must be following the rule #1.
- Two versions of Igel: 2.7.0 and 2.8.0 are excluded from network training/data generation process (both for data and for validation data) because they use Dietrich Kappe’s Night Nurse network as thus violate the rule #1.
- Data generation and network training must be done by myself on my own (or rented by me) hardware in order to make sure the rule #1 is not violated.
- Each generation of network must contain information on training parameters for clarity of the source of data.
- Complete source data of network may be given to tournament organizers for validation purposes and it must be possible for external parties to train the network from scratch using the provided data to the same strength as submitted network (margin of +-10 elo).
