Tactic Class Reference

Tactics are the basic building block for creating custom solvers for specific problem domains. The complete list of tactics may be obtained using Context.NumTactics and Context.TacticNames. It may also be obtained using the command (help-tactic) in the SMT 2.0 front-end. More...
