BARALG

This control determines which barrier algorithm is to be used to solve the problem.

Integer

-1	Determined automatically.
0	Unused.
1	Use the infeasible-start barrier algorithm.
2	Use the homogeneous self-dual barrier algorithm.
3	Start with 2 and optionally switch to 1 during the execution.

-1

The automatic setting uses 1 for LP and QP problems and 3 for QCQP problems. Usually the detection of primal or dual infeasibility is more robust with settings 2 or 3, therefore, it is advantageous to use one of these values if the model is presumably infeasible.
