Software created by members of the Optimization and Operational Research group
HiGHS is open-source software for linear optimization that has been developed by Julian Hall, Ivet Galabova, Leona Gottwald and Michael Feldmeier. It has solvers for linear programming (simplex and interior point), mixed-integer programming, and quadratic programming. Its overall performance in the industry standard benchmarks exceeds that of any other open source linear optimization software in the world. HiGHS provides the linear programming solvers in the SciPy system, and is available within the popular modern Julia-based modelling and optimization system JuMP. Future plans will see HiGHS available in Google's OR-Tools, Pyomo and OpenSolver. HiGHS is available from Github under the MIT license.
