Preamble :

I would like to improve AI

  • improve performance, Europe_WW1 is incredibly slow even threaded on good CPU. I guess it does way to much computations (this is my starting point, i am beginning investigations)
  • try to have mid term goals (like connect 3 nearest cities with road, for better unit movement)
  • try to define some strategic view with simple principles (make my territory convex, locate strategic places like a mountain controling a path or build a fortress to defend my frontier, only research caravel if landmass <30 and don't care if >45 ...)
  • have long term goals (like improve cities with schools then university )
  • at least stop doing incredibly stupid things like building tons of caravans (but this is rooted in decision making stuff, so in evaluation ...)

I think this will need changes in several places, including the server (for example reorder diplomacy ...)

My idea is to branch the code and affect several nations to reference AI, and other nations to a modified one , and let them fight to see if there are improvements or not.


So here is my question : how to do these tests ?

Is is possible to start several nations with 3.0.1 , and other ones with a patched version ?

(btw this could be a solution for WW1 : one instance for each nation, and a meta-server controlling all orders ?)

The simpler, and older, way to achieve something like this is by using the "Experimental" AI level (only available in builds with debug enabled). It's exactly the same as "Hard" level except for any changes you guard with "if (...->ai_common.skill_level == AI_LEVEL_EXPERIMENTAL)"

More involved one would be to set up entire AI modules for differentiating between players.
