The XA solver is a Linear Programming (LP) and Mixed Integer Programming (MIP) solver. For solving LP problems you can choose between the simplex algorithm and the (efficient) barrier algorithm. The MIP solver can only use the simplex algorithm.

Default AIMMS Solver

XA is available as the default linear solver in every AIMMS system for solving LP/MIP/QP.
