Evolutionary Algorithms as fitness function debuggers

Abstract : All Evolutionary Algorithms experienced practitioners emphasize the need for a careful design of the fitness function. It is commonly heard~ for instance, that "If there is a bug in your fitness function, the EA will find it". This paper presents a case study of such a situation in the domain of geophysical underground identification: some weird solutions are found by the Evolutionary Algorithm, obviously physically absurd, but fulfilling almost perfectly the geophysical criterion.
