FM has been implemented by Juan A. Rodríguez-Aguilar, Francisco J. Martín, Francisco J. Giménez, and David Gutiérrez.
However, FM is the result of a collective effort in which many more people have been involved. Thus, we would like to acknowledge:
Xavier Márquez manager of the Blanes fishermen's cooperative market (Blanes, Girona) for his illuminating explanations.
Pere Garcia, Pablo Noriega, Carles Sierra, Lluís Godo, Ramon López de Mántaras, Ulises Cortés, Julian Padget, Andreas Kind, Julio García, Maurizio Giordano, Claudia Di Napoli, and Mario Mango for their contributions to the evolution of the project up to the current stage.
