Maxim Method (String)

Note: This API is now obsolete.

Begins a search for the optimal LP solution.

Namespace:   Optimizer
Assembly:  xprsdn (in xprsdn.dll) Version: 44.01.01
Syntax
C# 
[ObsoleteAttribute("You should use LpOptimize/MipOptimize instead of Minim/Maxim/Global")]
public void Maxim(
	string flags
)

Parameters

flags
Type:  System.String
Flags to pass to maxim ( MAXIM) or minim ( MINIM). The default is "" or null, in which case the algorithm used is determined by the DEFAULTALG control. If the argument includes:
  • b: the problem will be solved using the Newton barrier method, or the Hybrid gradient method if BARALG is set to 4;
  • p: the problem will be solved using the primal simplex algorithm;
  • d: the problem will be solved using the dual simplex algorithm;
  • l: (lower case L), the problem will be solved as a linear problem ignoring the discreteness of MIP entities, unless the g flag is also provided (ref. note below);
  • n: (lower case N), the network part of the problem will be identified and solved using the network simplex algorithm;
  • g: the MIP problem will be solved by calling mipOptimize (MIPOPTIMIZE).
Certain combinations of options may be used where this makes sense so, for example, pg will solve the LP with the primal algorithm and then go on to perform the tree search.
