Encoding
At most one constraints (AMO) Quadratic encoding. not x1 \/ not x2 \/ x3 /\ the other combos logarithmic encoding. y is bitvector of which one is selected. heule encoding
Graph constraints
Tseitsin - encode subformulas into a variable

Stochastic local search solvers
Simple and sometimes good. DDFW Some examples: http://ubcsat.dtompkins.com/ http://fmv.jku.at/yalsat/ https://github.com/adrianopolus/probSAT matrix multiplication, problems with high symettry, graph coloring, pythoagorean triple problem
Seems very reasonable for max sat too?
