sifting from simplex switch

Turns on or off sifting from simplex optimization.

Purpose

Turns on or off sifting from simplex optimization

For more information about CPLEX sifting, see the topic Sifting optimizer in the CPLEX User's Manual.

Description

This switch turns on (or off) sifting from simplex optimization. By default, sifting from simplex optimization is on. That is, under appropriate conditions, CPLEX invokes sifting from simplex. If you want to force sifting, use the algorithm for continuous linear problems with the value 5 (CPX_ALG_SIFTING).

Table 1. Values
Value	Symbol	Meaning
1	`on`	default CPLEX executes sifting during simplex optimization under appropriate conditions.
0	`off`	CPLEX turns off sifting during simplex optimization.
