Formulações para o Problema da Compra Mínima
Abstract
We consider the Min-Buying Problem, where a seller wants to sell a set I of items to a set B of buyers. Each buyer b is willing to pay up to vib for item i. For this, the seller must define prices pi for each i ∈ I in order to maximize his profit considering that each buyer b will buy, if any, the most unexpensive item among those that pi ≤ vib. In this paper, we present and compare two integer linear programming formulations for such a problem.
