The Problem Description
Problem Description Use Case Objectives AMPL HiGHS
SERIES INTRO! # This is the first of eighteen videos over which we build an app for the awesome Rebrickable® community, which finds multiple LEGO® sets buildable concurrently from a user’s part inventory.
Model + Solver
Algebraic Modeling Languages Solvers Speed AMPL PYOMO GAMS CPLEX Gurobi HiGHS
A close look at large-scale optimization modeling tools and languages, and linear and nonlinear solvers.
Tune the Solver!!!
Solver Tuning Speed HiGHS
We explore the solving-time impact of our linear solver’s (HiGHS) various params/options, and use these to tune the solver for significantly faster performance on our optimization problem.
