There is no easy solution for that (I can't see it now). But practising the AI will be much faster... You are right it is difficult to evaluate such diverse games. Also number of games played on the server daily is probably quite low. I am able to run about 20-30 games daily on my PC (4 games in parallel!) If somebody is curious, I use these maps for testing Crater Four mountains Maze Crabsome island Some maps test ability to expand (without fighting) and some fighting.... The code contains four DNAs - winners from each map from a round - basically one winner daily per map / 4 winners in total. Edited: 2016-10-19, 19:49 UTC+2.0 Top Quote

Well usual approach for such testing is like 500 individuals and 10 best fitting are cloned for next generation. But this is obviously not possible with widelands (on one map) Top Quote

I do have a question, though: which game type(s) will you be using? An AI that does well in Wood Gnome may fare poorly in Endless Game, and one with revealed map may not do so well with fog of war. AI still does not distinguish these modes. Top Quote

If you only start from command line, you could add more though. This is nice. I have my testing environment settled now, but I think I will use it later. Thanks for effort... Top Quote

But the plan is very low mutation for "normal" AI so to avoid such irregularities as much as possible. It is far from "trained" yet Top Quote

I'll try to dig up original models in the media repository. ETA: No luck, so the existing images will need to be colorized by hand.

That said, try using the following colors for players 9-16: RGBColor(0, 120, 255), // sky blue RGBColor(104, 0, 40), // dark red RGBColor(120, 108, 0), // dark yellow RGBColor(0, 112, 0), // dark green RGBColor(255, 120, 160), // rose RGBColor(148, 56, 0), // brown RGBColor(96, 0, 84), // dark purple RGBColor(144, 144, 144), // light gray ...on a random note, at the bottom of the screenshots page, "a firy tournament" should read "a fiery tournament".
