End of list, stronger engines released before 2015 not listed (Critter, Equinox, Deep Junior, Naum, Quazar, Spark, others)
Unfortunately: Chiron isn't available so far!

Notes:
 go to start of site

- only one engine per programmer or group of programmers is counted = 200
- listed are engines that are likely to be in the TOP-175 or close to the TOP-175
- listed are strongest xb / JAVA / MCTS engines
- listed are no private engines
- listed are no engines the name of programmer is unknown, like:
 - 1. Bread - JA, 2. Expositor - JA, 3. Iris - JA, 4. Prelude, 5. Sirius - JA, 6. Stallion - D/L ...
- listed are CPU engines, no GPU engines, like: 1. Allie - JA, 2. Ara, 3. Ceres - JA ...

*1 = JAVA based engine, Java-JRE v8 upd 461, JDK v25, Node.js v24.8.0 (for Lozza)
*2 = HCE (Hand Crafted Evaluation). If not HCE then NN = Neural Network
