I am running a strong computer chess engine tournament, using arena 3.5.1 All engines are playing a large number of games. One engine appears to be glitching so I want to replace it with another alternative (in terms of CPU speed / compatibility) of the same version of the engine.

Is it possible to substitute one engine with another and retain the points that the other engine has already earned?

  • aren't YOU running the tournament ?

  • Yes. Hence why I am asking if there is a way of substituting and retaining the points. I know how to delete and engine and add another, but not how to retain / re-allocate points. Oct 20, 2016 at 14:52
  • Are you using a tournament manager software? What is it?

  • I am running the tournament within Arena 3.5.1. If this is what you mean. All new territory for me. Oct 20, 2016 at 14:55
  • @asibahi The question is about how to substitute a new version and not restart the tournament.

You can delete the old engine executable and copy a new one with the same filename to the same directory.
