Cloning mechanisms to improve agent performances

open access: yesJournal of Network and Computer Applications, 2013
Learning agents can autonomously improve both knowledge and performances by using learning strategies. Recently, an approach based on a cloning process, called EVolutionary Agents (EVA), has been proposed to obtain more effective recommendations, generating advantages for the whole agent community through individual improvements.
