RefineMipSol Method

Executes the MIP solution refiner. *@deprecated

Namespace:   Optimizer
Assembly:  xprsdn (in xprsdn.dll) Version: 40.01.03
Syntax
C# 
public void RefineMipSol(
	int options,
	string flags,
	double[] solution,
	double[] refined,
	out int p_status
)

Parameters

options
Type:  SystemInt32
Refinement options:
  • 0: Reducing MIP fractionality is priority (If bit 10 of REFINEOPS is set, will switch to other mode if unsuccessful).
  • 1: Reducing LP infeasibility is priority.
flags
Type:  SystemString
Flags passed to any optimization calls during refinement.
solution
Type:  SystemDouble
The MIP solution to refine. Must be a valid MIP solution.
refined
Type:  SystemDouble
The refined MIP solution in case of success
p_status
Type:  SystemInt32
Refinement results:
  • 0: An error has occurred
  • 1: The solution has been refined
  • 2: Current solution meets target criteria
  • 3: Solution cannot be refined
  • 5: The solution has been refined, but MIP fractionality could not be reduced.
