About:
HiGHS is a high-performance linear optimization solver designed for solving large-scale linear programming (LP), mixed-integer programming (MIP), and quadratic programming (QP) problems. It serves as a robust backend for modeling systems like Pyomo and JuMP, offering both primal and dual simplex methods as well as an interior-point solver. The software is widely used in operations research and supply chain management for finding optimal solutions to complex resource allocation problems.

Key Features:

Dual and primal simplex solvers
Interior-point solver for LP
High-performance branch-and-bound MIP solver
Support for quadratic programming (QP)
C++ library with C, Fortran, and Python interfaces

Use Cases:

Supply chain and logistics optimization
Financial portfolio optimization
Production scheduling and resource allocation
Energy system modeling

Alternatives:

CBC – Open-source MIP solver; generally slower than HiGHS on large-scale problems
Gurobi – Commercial solver with superior performance but restrictive licensing
SCIP – Open-source framework with strong MIP capabilities but more complex setup
