XSLP_PRESOLVELEVEL

This control determines the level of changes presolve may carry out on the problem

Integer

XSLP_PRESOLVELEVEL_LOCALIZED	Individual rows only presolve, no nonlinear transformations.
XSLP_PRESOLVELEVEL_BASIC	Individual rows and bounds only presolve, no nonlinear transformations.
XSLP_PRESOLVELEVEL_LINEAR	Presolve allowing changing problem dimension, no nonlinear transformations.
XSLP_PRESOLVELEVEL_FULL	Full presolve.

XSLP_PRESOLVELEVEL_FULL

XSLP_PRESOLVEOPS and XSLP_REFORMULATE controls the operations carried out in presolve. XSLP_PRESOLVELEVEL controls how those operations may change the problem.
