Detailed Description
template<class SearchPointType>
class shark::AbstractConstraintHandler< SearchPointType >
Implements the base class for constraint handling.
A constraint handler provides information about the feasible region of a constrained optimization problem. In the minimum it checks whether a point is feasible, or what the next fasible point would be.
