WebThe feasibility relaxation is a model that, when solved, minimizes the amount by which the solution violates the bounds and linear constraints of the original model. This method provides a number of options for specifying the relaxation. WebA problem proposed by Gurobi "Look how binary is the form, the nature of things. Ones and zeros. Choice and its absence." — Agent Smith, The Matrix Resurrections This repository provides models for solving "The Matrix: Revisited" problem, introduced by the folks from Gurobi in the following video: Holiday Tech Talk - Santa’s Bag of Interesting & Unusual …
