Changes the type of the delta assigned to a nonlinear variable

Namespace:  Optimizer
Assembly: xprsdn (in xprsdn.dll) Version: 45.01.02+1f9fd7ff9a8620394fec1839699751312debed40
Syntax
C# 
public void SlpChgDeltaType(
	int nvars,
	int[] varind,
	int[] deltatypes,
	double[] values
)

Parameters

nvars   Int32
The number of SLP variables to change the delta type for.
varind   Int32
Indices of the variables to change the deltas for.
deltatypes   Int32
Type of the delta variable:
  • 0 (XSLP_DELTA_CONT): Differentiable variable, default.
  • 1 (XSLP_DELTA_SEMICONT): Variable where a minimum perturbation size given in values may be required before a significant change in the problem is achieved.
  • 2 (XSLP_DELTA_INTEGER): Variable defined over the grid size given in values.
  • 3 (XSLP_DELTA_EXPLORE): Variable where a meaningful step size should automatically be detected, with an upper limit given in values.
values   Double
Grid or minimum step sizes for the variables.
