[Computer-go] February KGS bot tournament: 19x19

[steve uurtamo]

it's something like halfway between fisher time and absolute time.

think of the number of byo-yomi periods as the number of times you are
allowed to think for an excessive amount of time before losing the
game by default. (where "excessive" is defined by the length of each
byo-yomi period). when you go over a byo-yomi period, you lose it
forever. when you don't, you keep it.

play some go on a server like kgs to get a feel for how this works.

think of the main time as the amount of time that you can do whatever
you please.

as examples:

i've seen some people play 1:00 main time, 100x10s byo-yomi.
i've seen others play 30:00 main time, 5x30s byo-yomi.

it should be clear that the playing style (and therefore the strategy)
of these two time settings is completely different.

in computer go, time control is nontrivial to deal with, but the main
time is usually long enough to get to endgame moves. or perhaps should
be considered as same. crazy time schedules like my first example are
rare in computer tournaments that i've seen.

i'm really curious to hear how various programs handle their time
controls -- it seems like an important choice; perhaps this is an
easily solved problem?
