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?
Crossword puzzles are a popular pastime. We design and build Mixed Integer Linear Programming models to compile crossword puzzles.
Bin packing is a common optimization problem. A new formulation helps us solve a simple, yet difficult to solve, bin packing model.
Job sequencing is a common problem. Excel Solver can help managers make optimal job sequencing decisions to minimize cost.
Designing an optimization model is difficult. This article explains common mathematical notation used to define optimization model formulations.
We minimize trim waste in a paper manufacturing process. A theoretically perfect solution is impractical, so what can we do?
The selection of a better fantasy sports team can substantially improve performance. Excel plus OpenSolver can pick an optimal team.
We experiment with the new Python in Excel feature, building and solving a linear program using the Python SciPy library.
