Description
Sets which algorithm to use when the C routine CPXqpopt
(or the command optimize
in the Interactive Optimizer) is invoked.
Currently, the behavior of the Automatic setting is that CPLEX invokes the Barrier Optimizer for continuous QP models. The Automatic setting may be expanded in the future so that CPLEX chooses the algorithm based on additional problem characteristics.
