In this setting, different individuals are exposed to different experiences. This may happen because the world surrounding an agent changes over time or because we allow agents exploring different parts of the world. The algorithm permits the exchange of chromosomes from different agents and combines two different evolution strategies, one based on Darwin's and the other on Lamarck's evolutionary theory. Experiments on a problem of digital circuit diagnosis and on the $n$-queen problem show that the addition of the Lamarckian operator in the single agent case improves the fitness of the best solution, even if in the digital circuit case the fitness difference is not significant. Moreover, the experiments show that the distribution of constraints, even if it leads to a decrease of the fitness of the best solution, does not produce a significant difference.}, year = {2002}, publisher = {CSREA}, address = {Bogart, Georgia, \USA}, keywords = {Genetic Algorithms,Theory Revision}, month = jun, pages = {1--7}, http = {http://www.lip.uns.edu.ar/cmsra/lamma.pdf}, pdf = {http://ml.unife.it/wp-content/uploads/Papers/LamRigPer-CMSRA02.pdf} }
