Given available stock of wire and a list of pieces required, what is the best way to cut the stock to fulfil demand while minimizing waste?
We've collated links to dozens of websites about optimization modelling. The links are organized into several categories.
We describe an example of how to represent price breaks in a linear programming model, built in Excel using Solver or OpenSolver.
We explore two aspects of refactoring an existing optimization model: Modularization and adding model variations.
We compare a linear programming model written using Julia/JuMP with the same model written using Python/Pyomo.
This article series implements a staff scheduling model in Excel using OpenSolver, then in Python using Pyomo.
We estimate the speed improvement for optimization solvers in the 35 years from 1989 to 2024. The results may be surprising.
Bin packing is a common optimization problem. A new formulation helps us solve a simple, yet difficult to solve, bin packing model.
