1. A system for selecting a solution, comprising: a first computer, for generating a first population of solutions, the first population of solutions being of a first representation scheme; a second computer, for generating a second population of solutions, the second population of solutions being of a second representation scheme; a translator for translating solutions of the second representation scheme into equivalent solutions of the first representation scheme; means for introducing solutions from the second population of solutions into the first population of solutions; and means for evaluating solutions of the first population of solutions according to a preselected evaluation function.
