operations_research::ScipConstraintHandlerContext::ScipConstraintHandlerContext	(	SCIP *	scip,

A value of nullptr for solution means to use the current LP solution.

bool operations_research::ScipConstraintHandlerContext::is_pseudo_solution ( ) const

inline

Pseudo solutions may not be LP feasible. Duals/reduced costs are not available (the LP solver failed at this node).

Do not add "user cuts" here (that strengthen LP solution but don't change feasible region), add only "lazy constraints" (cut off integer solutions).
