XKTR_PARAM_MIP_LPALG

Description
Specifies which algorithm to use for any linear programming (LP) subproblem solves that may occur in the MIP branch and bound procedure.
Type
Integer
Values
0 
(auto) Let Knitro automatically choose an algorithm, based on the problem characteristics.
1 
(direct) Use the Interior/Direct (barrier) algorithm.
2 
(cg) Use the Interior/CG (barrier) algorithm.
3 
(active) Use the Active Set (simplex) algorithm.
Default value
0
Note
LP subproblems may arise if the problem is a mixed integer linear program (MILP), or if using XKTR_PARAM_MIP_METHOD = HQG. (Nonlinear programming subproblems use the algorithm specified by the algorithm option.)
