[Freeciv-Dev] land grab AI improvement

[Alain Vicet <alain@xxxxxxxxxxxx>]

hi,

I noted some side-effects after applying aicheat3.diff patch : on easy level,
city growing is very slow because settlers didn't cheat (tile which are not
unveil are not targetted).

I think, I can improve the land grab phase (both in easy and hard
level):
- speed explorer search,
- speed city creation with settlers,
- use unit with no home city (I call them free unit) to explore the rest of the
  world.

I think it's possible with no side-effect with other phases,... I hope :-).

I noted too, some optimisation in coordonate.diff patch (use map_get_tile(gx, 
gy)->assigned rather a new list)

I will able to sugest you a big patch in one week. If you want I can send you a
patch of my present development (present patch size is about 200ko).
