Description
Decides whether node presolve should be performed at the nodes of a mixed integer programming (MIP) solution. Node presolve can significantly reduce solution time for some models. The default setting is generally effective at deciding whether to apply node presolve, although runtimes can be reduced for some models by the user turning node presolve off.
