Detailed Description

Probes are used to inspect a goal (aka problem) and collect information that may be used to decide which solver and/or preprocessing step will be used. The complete list of probes may be obtained using the procedures Context.NumProbes and Context.ProbeNames. It may also be obtained using the command (help-tactics) in the SMT 2.0 front-end.
