RepairWeightedInfeas Method (IDictionary(Inequality, Double), IDictionary(Inequality, Double), IDictionary(Variable, Double), IDictionary(Variable, Double), Char, Double, String)

Repair infeasibilities using weights. By relaxing a set of selected constraints and bounds of an infeasible problem, it attempts to identify a 'solution' that violates the selected set of constraints and bounds minimally, while satisfying all other constraints and bounds. Among such solution candidates, it selects one that is optimal regarding the original objective function.

Syntax
C# 
public int RepairWeightedInfeas(
	IDictionary<Inequality, double> lepref,
	IDictionary<Inequality, double> gepref,
	IDictionary<Variable, double> lbpref,
	IDictionary<Variable, double> ubpref,
	char phase2,
	double delta,
	string flags
)

Parameters

lepref
Type:  System.Collections.Generic.IDictionary < Inequality, Double >
Map with preferences for relaxing the less-than-or-equal direction of rows. Inequalities without preference will not be relaxed. Can be null.
gepref
Type:  System.Collections.Generic.IDictionary < Inequality, Double >
Map with preferences for relaxing the greater-than-or-equal direction of rows. Inequalities without preference will not be relaxed. Can be null.
lbpref
Type:  System.Collections.Generic.IDictionary < Variable, Double >
Map with preferences for relaxing the lower bounds of variables. Variables without preference will not be relaxed. Can be null.
ubpref
Type:  System.Collections.Generic.IDictionary < Variable, Double >
Map with preferences for relaxing the upper bounds of variables. Variables without preference will not be relaxed. Can be null.
phase2
Type:  System.Char
Controls the second phase of optimization.
delta
Type:  System.Double
Relaxation multiplier in second phase - 1.
flags
Type:  System.String
Flags passed to the optimizer.

Return Value

Type:  Int32
Result status.
