We present an example of project crashing using an optimization model to help the project manager decide what to do.
The selection of a better fantasy sports team can substantially improve performance. Excel plus OpenSolver can pick an optimal team.
Crossword puzzles are a popular pastime. We design and build Mixed Integer Linear Programming models to compile crossword puzzles.
We replicate a wood cutting pattern model from a published academic paper. Surprisingly, we find a better optimal solution.
Why does my model find different solutions? Some solutions are better than others – how can that be true? How do I find the overall best solution?
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 estimate the speed improvement for optimization solvers in the 35 years from 1989 to 2024. The results may be surprising.
Designing an optimization model is difficult. This article explains common mathematical notation used to define optimization model formulations.
