It becomes necessary to prune the list for the following reasons:
1. It takes resources and time to finish the gauntlet matches.
2. Some engines are annoyance to viewers which may just be a near 100% clone of another engine.
3. It is not maintained anymore.
Though there are more engines that need to be be taken away, there are no good substitutes to take its place in the strongest engines category. It will go away when another new strong engine will appear.
The initial engines that vanished were Robodini 1.1 x64, ComStock 3 x64 and Ryanfish 1 x64 but they were still retained in the rating list for historical purpose.
