We replicate a wood cutting pattern model from a published academic paper. Surprisingly, we find a better optimal solution.
Crossword puzzles are a popular pastime. We design and build Mixed Integer Linear Programming models to compile crossword puzzles.
The selection of a better fantasy sports team can substantially improve performance. Excel plus OpenSolver can pick an optimal team.
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 minimize trim waste in a paper manufacturing process. A theoretically perfect solution is impractical, so what can we do?
Given available resources, what mix of products will maximize profit? We can answer to question using Excel and the Solver add-in.
We describe an example of how to represent price breaks in a linear programming model, built in Excel using Solver or OpenSolver.
Bin packing is a common optimization problem. A new formulation helps us solve a simple, yet difficult to solve, bin packing model.
