How to Use

A brief example that solves a simple SAT problem:

# solve (a or b) and (not a or b) and (a or not b)

require "minisat"
solver = MiniSat::Solver.new

a = solver.new_var
b = solver.new_var

solver << [a, b] << [-a, b] << [a, -b]

p solver.solve  #=> true (satisfiable)

p solver[a]  #=> true
p solver[b]  #=> true
