چکیده

The close links that now exist between biology and computation raise the prospect of setting species evolution in a broader, computational context. This context would comprise theories about the origins of pattern and order in complex systems. We argue that several processes play crucial roles in both natural and artificial evolution. One mechanism consists of critical changes between different system phases that promote order and variation respectively. Processes that lead to modular structures promote both robustness and increasing complexity in evolution. Examples of such processes include genetic convergence, gene shuffling and ordered asynchronous processing. We demonstrate that gene shuffling causes colocation of genes on chromosomes, thus promoting genetic modularity.

Prediction of Surface Roughness by Hybrid Artificial Neural Network and Evolutionary Algorithms in End Milling

Machining processes such as end milling are the main steps of production which have major effect on the quality and cost of products. Surface roughness is one of the considerable factors that production managers tend to implement in their decisions. In this study, an artificial neural network is proposed to minimize the surface roughness by tuning the conditions of machining process such as cut...

Appraisal of the evolutionary-based methodologies in generation of artificial earthquake time histories

Through the last three decades different seismological and engineering approaches for the generation of artificial earthquakes have been proposed. Selection of an appropriate method for the generation of applicable artificial earthquake accelerograms (AEAs) has been a challenging subject in the time history analysis of the structures in the case of the absence of sufficient recorded accelerogra...

An Evolutionary Multi-objective Discretization based on Normalized Cut

Learning models and related results depend on the quality of the input data. If raw data is not properly cleaned and structured, the results are tending to be incorrect. Therefore, discretization as one of the preprocessing techniques plays an important role in learning processes. The most important challenge in the discretization process is to reduce the number of features’ values. This operat...
