RE: [computer-go] Time constraints for computer Go

["David Fotland" <fotland@xxxxxxxxxxxxxxx>]

Use a binary editor to find the arrays that control the searches and
change the values in them:

/* LEVELS:    1  2  3  4  5  6  7  8   9  10  */
int maxmoves[NUMLEVELS] =   /* maximum number of moves to try on full board
*/
        {  0, 3, 3, 5, 5, 5, 6, 7, 8, 10, 15 };  /* can look at more if have
extra time */
int maxvariations[NUMLEVELS] =  /* max number of children per move tried */
        {  0, 1, 1, 2, 2, 3, 3, 4, 5,  5,  5 };
char maxscorebrdepth[NUMLEVELS] =	/* max depth for any branches in Q
search */
		{  0, 0, 0, 1, 1, 2, 2, 2, 3,  3,  3 }; 
char maxscoredepth[NUMLEVELS] = /* max depth for local q search, other than
tac captures */
        {  0, 0, 0, 1, 1, 2, 2, 3, 3,  3,  3 };
int maxlifecalls[NUMLEVELS] =  /* should be around maxmoves*maxvariations */
        {  0, 5,10,25,50,100,200,300,500,1000,2000 };

etc.

Should be easy :)
