folding for LP models

Decides whether LP folding will be attempted during the preprocessing phase.

Purpose

indicator for folding of LP models

API Parameter Name C CPXPARAM_Preprocessing_Folding C++ IloCplex::Param::Preprocessing::Folding Java IloCplex.Param.Preprocessing.Folding .NET Cplex.Param.Preprocessing.Folding OPL folding Python parameters.preprocessing.folding Interactive preprocessing folding Identifier 1164

Description

Decides whether folding will be automatically executed, during the preprocessing phase, in a LP model. The default level, -1, allows CPLEX to choose the degree of folding to apply. The value 0 (zero) turns off folding. Levels 1 through 5 apply increasingly aggressive folding.

Table 1. Values

Value	Meaning
-1	Automatic: let CPLEX choose; default
0	Turn off folding
1	Exert a moderate level of folding
2	Exert an aggressive level of folding
3	Exert a very aggressive level of folding
4	Exert a highly aggressive level of folding
5	Exert an extremely aggressive level of folding
