About AvatarSAT
AvatarSAT is a SAT solver that uses machine-learning classifiers
to automatically tune the heuristics of an off-the-shelf SAT solver on
a per-instance basis. The classifiers use features of both the input
and conflict clauses to select parameter settings for the solver's
tunable heuristics. On a randomly selected set of SAT problems chosen
from the 2007 and 2008 SAT competitions, AvatarSAT is, on the average,
three times faster per problem than MiniSAT based on the geometric
mean speedup measure and two times faster per problem based on the
arithmetic mean speedup measure. Moreover, AvatarSAT is hundreds to
thousands of times faster than MiniSAT on many hard SAT instances and
is never more than twenty times slower than MiniSAT on any SAT
instance.
