We estimate the speed improvement for optimization solvers in the 35 years from 1989 to 2024. The results may be surprising.
This series explores optimization of a "picking warehouse" by improving the warehouse design and efficiency of the picking process.
We experiment with the new Python in Excel feature, building and solving a linear program using the Python SciPy library.
We explore two aspects of refactoring an existing optimization model: Modularization and adding model variations.
We've collated many interesting optimization models in our GitHub repository. The focus is on Excel and Python models.
The selection of a better fantasy sports team can substantially improve performance. Excel plus OpenSolver can pick an optimal team.
Designing an optimization model is difficult. This article explains common mathematical notation used to define optimization model formulations.
Crossword puzzles are a popular pastime. We design and build Mixed Integer Linear Programming models to compile crossword puzzles.
