Comparative analysis of mathematical formulations for the two-dimensional guillotine cutting problem
Henrique Becker, Mateus Martin, Olinto Araujo +2
About ten years ago, a paper proposed the first integer linear programming formulation for the constrained two-dimensional guillotine cutting problem (with unlimited cutting stages…
A biased random-key genetic algorithm for the home health care problem
Alberto F. Kummer, Olinto C. B. de Araújo, Luciana S. Buriol +1
Home health care problems consist of scheduling visits to home patients by health professionals while following a series of requirements. This paper studies the Home Health Care Ro…
Enhanced Formulation for Guillotine 2D Cutting Problems
Henrique Becker, Olinto Araujo, Luciana S. Buriol
We advance the state of the art in Mixed-Integer Linear Programming (MILP) formulations for Guillotine 2D Cutting Problems by (i) adapting a previously known reduction to our prepr…
An empirical analysis of exact algorithms for the unbounded knapsack problem
Henrique Becker, Luciana S. Buriol
This work presents an empirical analysis of exact algorithms for the unbounded knapsack problem, which includes seven algorithms from the literature, two commercial solvers, and mo…
Preferential attachment in the growth of social networks: the case of Wikipedia
A. Capocci, V. D. P. Servedio, F. Colaiori +4
We present an analysis of the statistical properties and growth of the free on-line encyclopedia Wikipedia. By describing topics by vertices and hyperlinks between them as edges, w…
