--- Comment #1 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
yes good call.  i have branch-decision execution working (6 months ago), it
needs a proper decision system.

i really liked the BOOM algorithm, it should be in here:

the reason it was good was because it adapted very quickly yet got things
right a lot.
