What sort of problem solving methods is supported by the eplex library?
The exact method used to solve the problem is determined by the solver. The eplex library does provide options to specify the solving method that should be used, but this will only be meaningful if the solver supports the specified method. The common solving methods are: Simplex (primal and dual), and interior point (barrier) methods. Note that some solvers places restrictions on the problem types that can be solved by a particular method. In addition, for commercial solvers, your license may limit the solving methods you can use.
