"Real continuous submodular functions, as a generalization of the corresponding discrete notion to domain, gained considerable attention recently. The analog for entropy functions requires additional properties: real function defined on non-negative orthant $\R^n$ is entropy-like (EL) if it submodular, takes zero at zero, non-decreasing, and has Diminishing Returns property. Motivated by proble...

due to the algorithmic simplicity, cellular automata (ca) models are useful and simple methods in structural optimization. in this paper, a cellular-automaton-based algorithm is presented for simultaneous shape and topology optimization of continuum structures, using five-step optimization procedure. two objective functions are considered and the optimization process is converted to the single ...

Blind source separation technique separates mixed signals blindly without any information on the mixing system. In this paper, we have used two evolutionary algorithms, namely, genetic algorithm and particle swarm optimization for blind source separation. In these techniques a novel fitness function that is based on the mutual information and high order statistics is proposed. In order to evalu...
