Purpose
Initiate the Xpress Nonlinear mixed integer SLP (MISLP) algorithm
Synopsis
problem.globalsol ()
Example
The following example solves the continuous relaxation of the problem and then finds the integer solution.
p.nlpoptimize () p.globalsol ()
Further information
The current Xpress Nonlinear mixed integer problem will be maximized or minimized using the algorithm defined by the control variable xslp_mipalgorithm.
It is recommended that problem.nlpoptimize be used first to obtain a converged solution to the relaxed problem. If this is not done, ensure that xslp_ojsense is set appropriately.
See the chapter on Mixed Integer Non-Linear Programming in the SLP Reference Manual for more information about the Xpress Nonlinear MISLP algorithms.
