[freeciv-ai] RFC: Behaviour constants.

[Gregory Berkolaiko <Gregory.Berkolaiko@xxxxxxxxxxxx>]

How can we improve AI without going too deep?

This is a legitimate question, and an answer to it is given by various 
constants and factors and multipliers that the AI code is peppered with.  
Examples are: what is considered to be a small nation (number of cities) 
-- used to encourage settler building; what is the default danger for 
capital; what is food/shield weighting etc.

Some of these numbers are defines, some are just plain numbers.  What I 
propose is to collect them all in some .h file included in all AI files, 
so they can be tweaked in a systematic way.  Then tweak them and run 
pitfights, lots of them.  There ar, of course difficulties like "constant 
is constant for all nations", but they are solvable.

A note on pitfights: when I did it, I used Per's script, but slightly 
modified.  I would run a gmame with two players H and E, and each map 
would be run twice, the second time with E in H's starting position and 
vice versa.  Then if E would lose both games I knew my changes were making 
it weaker; if E won both games, it was becoming stronger.

Best wishes,
