int SCIPvarGetLastBdchgDepth

(

SCIP_VAR *

var

)

returns the last depth level, at which the bounds of the given variable were tightened; returns -2, if the variable's bounds are still the global bounds returns -1, if the variable was fixed in presolving

Parameters

var	problem variable

SCIP_Bool SCIPvarWasFixedEarlier	(	SCIP_VAR *	var1,
