Barrier Optimizer in the CPLEX Callable Library (C API) Reference Manual

These routines support applications that solve linear programs by means of the CPLEX barrier optimizer.

CPXXbaropt and CPXbaropt
The routine CPXXbaropt/CPXbaropt may be used to find a solution to a linear program (LP), quadratic program (QP), or quadratically constrained program (QCP) by means of the barrier algorithm at any time after the problem is created by a call to CPXXcreateprob/CPXcreateprob.
CPXXhybbaropt and CPXhybbaropt
The routine CPXXhybbaropt/CPXhybbaropt may be used, at any time after a linear program has been created via a call to CPXXcreateprob/CPXcreateprob, to find a solution to that problem.
