We estimate the speed improvement for optimization solvers in the 35 years from 1989 to 2024. The results may be surprising.
Allocating people to teams is a task common in both sport and business. We allocate 32 people to 4 teams that are as balanced as possible.
Bin packing is a common optimization problem. A new formulation helps us solve a simple, yet difficult to solve, bin packing model.
We experiment with the new Python in Excel feature, building and solving a linear program using the Python SciPy library.
Sometimes we need more power to solve a model. This article describes how to solve a model using the CPLEX solver via the NEOS Server.
We've collated many interesting optimization models in our GitHub repository. The focus is on Excel and Python models.
We've collated links to dozens of websites about optimization modelling. The links are organized into several categories.
How many other optimal solutions exist? How do I find those solutions. This article explains how to use the CPLEX solution pool.
