/**Function********************************************************************
Synopsis [Tries to solve formulas in groups belonging to the solver
except the groups in the list.]
Description [The permanent group must not be in the list.
Returns a flag whether the solving was successful. If it was successful only
then SatSolver_get_model may be invoked to obtain the model ]
SideEffects []
SeeAlso [SatSolverResult,SatSolver_get_permanent_group,
SatIncSolver_create_group, SatSolver_get_model]
