MP-Opt-Model Version 3.0 08-Oct-2020 MP-Opt-Model is a package of MATLAB/Octave M-files for constructing and solving mathematical optimization problems. It provides an easy-to-use, object-oriented interface for building and solving your optimization model. It also includes a unified interface for calling numerous LP, QP, mixed-integer and nonlinear solvers, with the ability to switch solvers by simply changing an input option. It is based on code that was originally developed by Ray D. Zimmerman of Cornell University as part of MATPOWER. The latest version of MP-Opt-Model can be found on GitHub at: https://github.com/MATPOWER/mp-opt-model MIPS is covered by the 3-clause BSD License (see LICENSE for details).
