If bit 1 of xslp_presolve is not set, no nonlinear presolve will be performed. Otherwise, the presolve will be performed in accordance with the bit settings. problem.presolve is called automatically by problem.construct, so there is no need to call it explicitly unless there is a requirement to interrupt the process between presolve and optimization. problem.presolve must be called before problem.construct or any of the SLP optimization procedures.
