RefineMipSol Method

Note: This API is now obsolete.

Executes the MIP solution refiner.

Namespace:   Optimizer
Assembly:  xprsdn (in xprsdn.dll) Version: 44.01.01
Syntax
C# 
[ObsoleteAttribute("Obsolete since version 38.00", false)]
public void RefineMipSol(
	int options,
	string flags,
	double[] solution,
	double[] refined,
	out int p_status
)

Parameters

options
Type:  System.Int32
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:  System.String
Flags passed to any optimization calls during refinement.
solution
Type:  System.Double
The MIP solution to refine. Must be a valid MIP solution.
refined
Type:  System.Double
The refined MIP solution in case of success
p_status
Type:  System.Int32
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.
