| Abstract | We present in this paper an application of the Constructive Genetic Algorithm (CGA) to the Generalized Assignment Problem (GAP). The CGA presents some new features compared to a traditional genetic algorithm (GA), such as a population formed only by schemata, recombination among schemata, dynamic population, mutation in complete structures, and the possibility of using heuristics in schemata and/or structure representation. The GAP can be described as a problem of assigning n items to m knapsacks, n>m, such that each item is assigned to exactly one knapsack, subject to capacity constraints on the knapsacks. In our application of CGA to GAP, we regard the GAP as a clustering problem. A binary representation is used for schemata and structures, and an assignment heuristic allocates items to knapsacks. Schemata do not consider all the problem data. The schemata are recombined, and they can produce new schemata or structures. New schemata are evaluated and can be added to the population if they pass an evolution test. Structures can result from recombination of schemata or complementing of good schemata. They suffer mutation and the best structure generated is kept in the process. Computational tests have been performed using instances of large scale available in the literature. |
