TUNERROOTALG

This control is deprecated, and is provided for compatibility purposes. Please use LPFLAGS instead. It is a bit-vector control which defines the algorithm for solving an LP problem or the initial LP relaxation of a MIP problem within the tuner specifically.

Integer

Bit	Meaning
0	Use the dual simplex method.
1	Use the primal simplex method.
2	Use the barrier method.
3	Use the network simplex method.

0

Setting bit 0, 1, 2, 3 of this control will have the same effect of passing flags d, p, b, n to XPRSmipoptimize or XPRSlpoptimize. When more than one bit are set, then the LP problem will be solved with the concurrent solver.

This control only has an effect on the tuner.

This control can be tuned.
