  • Crossover and Diversity: A Study about GVR  
  • by Jorge Tavares Pinhal, Jorge Tavares, Francisco B. Pereira — 2003
  • …Genetic Vehicle Representation (GVR) is a two level representational scheme, designed to deal in an e#ective way with all the information needed by candidate solutions, for the Vehicle Routing Problem (VRP). In this paper, we present an analysis on the influence of two crossover operators in t…

  • On the Influence of GVR in Vehicle Routing  
  • by Jorge Tavares Pinhal, Jorge Tavares, Penousal Machado — 2003 — In Proceedings of the 2003 ACM Symposium on Applied Computing
  • …A comparative study is made between a new evolutionary approach for the Vehicle Routing Problem (VRP) and a standard evolutionary model, based on Path Representation. Genetic Vehicle Representation (GVR) is the new twolevel representational scheme designed to deal in an e#ective way with all the inf…

  • GVR: a new genetic representation for the vehicle routing problem  
  • by Francisco B. Pereira, Jorge Tavares, Penousal Machado, Ernesto Costa — 2002 — Problem, Proceedings of the 13th Irish Conference on Artificial Intelligence and Cognitive Science
  • …Abstract. In this paper we analyse a new evolutionary approach to the vehicle routing problem. We present Genetic Vehicle Representation (GVR), a two-level representational scheme designed to deal in an effective way with all the information that candidate solutions must encode. Experimental results…

  • GVR Delivers It On Time  
  • by Jorge Tavares, Francisco B. Pereira, Penousal Machado, Ernesto Costa — 2002 — In SEAL02 4th Asia-Pacific Conference on Simulated Evolution And Learning
  • …Genetic Vehicle Representation (GVR) is a new two-level representational scheme designed to encode all the information required by potential solutions for the vehicle routing problem. In a previous paper we described a set of experiments performed with several instances from the Capacitated Vehicle …

  • Vehicle routing problem: Doing it the evolutionary way  
  • by Penousal Machado, Jorge Tavares, Francisco B. Pereira, Ernesto Costa — 2002 — In GECCO 2002: Proceedings of the Genetic and Evolutionary Computation Conference
  • …In this paper we describe three evolutionary approaches to the vehicle routing problem. In our first approach we use a standard genetic algorithm whilst in the second we use a coevolutionary model. The third approach concerns the extension of the previous ones through the inclusion of heuristics. We…

  • Evolving Creativity  
  • by Penousal Machado Jorge, Jorge Tavares, Amílcar Cardoso, Francisco B. Pereira, Ernesto Costa — 2004
  • …Transformational creativity requires a change of the search space. As such, Evolutionary Computation (EC) approaches are incapable of transformational creativity. In this paper, we discuss how canonical EC techniques can be extended in order to yield the potential of transformational creativity.…
