LPFLAGS

Description
A bit-vector control which defines the algorithm for solving an LP problem or the initial LP relaxation of a MIP problem.
Type
Integer
Values
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.
Default value
0
Note

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. When this control is set and flags are passed at the same time, the flags will overrule the value of the control.

This control can be tuned.
Affects routines
XPRSlpoptimize ( LPOPTIMIZE), XPRSmipoptimize ( MIPOPTIMIZE).
