i programmed a checkers program, and use something like this to generate an
opening book. i take the initial position, and have my engine search each
possible move. once done, these values are stored to disk. then i go on
expanding more promising lines (with higher values), but also expand less good
lines, just to make sure it doesnt miss anything. i've had this thing running
for weeks for some checkers openings, and i can just switch it off anytime i
want, and back on again when i have spare computer time for it. it's really nice
:-)
i use this for the opening book generation, but in principle you can use exactly
this method to do a search anywhere.
