We estimate the speed improvement for optimization solvers in the 35 years from 1989 to 2024. The results may be surprising.
How many other optimal solutions exist? How do I find those solutions. This article explains how to use the CPLEX solution pool.
Crossword puzzles are a popular pastime. We design and build Mixed Integer Linear Programming models to compile crossword puzzles.
This series explores optimization of a "picking warehouse" by improving the warehouse design and efficiency of the picking process.
Bin packing is a common optimization problem. A new formulation helps us solve a simple, yet difficult to solve, bin packing model.
This series of 13 articles compares Python libraries Pyomo, PuLP, OR-Tools, Gekko, CVXPY, and SciPy for building a linear programming model.
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 present an example of project crashing using an optimization model to help the project manager decide what to do.
