Detailed Description

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-tactics) 

in the SMT 2.0 front-end.
