Rebel - UCI engines Rating CEDR=3476 (15 place)  Thanks to the author : Ed Schroeder  Website    v.16: Rebel 16 is the next step in the cooperation between Ed Schröder (Rebel) and Chris Whittington (Chess System Tal). 1. Rebel 16 uses the search code of Chess System Tal but comes with its own (much improved) network evaluation. 2. Rebel 16 will be the last version. 3. Now that our work is fully exchangeable (engine and network) Ed will fully devote his time on improving Chess System Tal.

  Chess engine: Viridithas Rating CEDR=2949 v.5.1.0: Viridithas 5.1.0 adds restrictions to the pruning heuristics in Viri's search, deactivating them when mate scores are detected. This improves the speed at which Viridithas solves tactical test positions. I would expect this to improve Viri's strength in some rare positions, but it does not have a significant effect in standard play.
