QCROOTALG

This control determines which algorithm is to be used to solve the root of a mixed integer quadratic constrained or mixed integer second order cone problem, when outer approximation is used.

Integer

-1	Determined automatically.
0	Use the barrier algorithm.
1	Use the dual simplex on a relaxation of the problem constructed using outer approximation.

-1

This control only has an effect if MIQCPALG is set to 1.

XPRSmipoptimize ( MIPOPTIMIZE), XPRSminim ( MINIM), XPRSmaxim ( MAXIM), XPRSglobal ( GLOBAL).
