We study both genotypic and phenotypic convergence in GP floating point continuous domain symbolic regression over thousands of generations. Subtree fitness variation across the population is measured shown many cases to fall. In an expanding region about root node, genetic opcodes function evaluation values are identical or nearly identical. Bottom up (leaf root) analysis shows syntactic seman...

Computer-assisted methods have become very important in analyzing biosequence data. However, most of the current methods are limited to nding motifs only. Genes can be regulated in many ways, including combinations of regulatory elements. This research is aimed at combinatorial motif analysis and hypothesis generation. A genome-wide gene expression analysis demonstrated the value of the studies...

In a global economy, an efficient supply chain as a main core competency empowers enterprises to provide products or services at the right time in the right quantity, at a low cost. This paper is to plan a single product, multi-echelon, multi-period closed loop supply chain for high-tech products (which have continuous price decrease). Ultimately, considering components rated to procurement, pr...

at this study, after designing and manufacturing a rotary tool, its machining parameters and their effects on surface roughness of aluminum alloy of al99 which  is one of the most consumable alloys in aerospace industry, is  studied and optimized. first, the rotary tool is designed and manufactred. then according to taguchi method, the experiments have been designed to record surface roughness,...

abstract— in the present study, genetic programming (gp) as a completely different approach in comparison with conventional methods, based on the imitation of natural evolution of living organism is proposed for the prediction of cellulose acetate (ca) polymeric membrane characteristics. the membrane preparation parameters of polymer concentration, additive concentration and coagulation bath te...

in this paper, a comprehensive model is proposed to design a network for multi-period, multi-echelon, and multi-product inventory controlled the supply chain. various marketing strategies and guerrilla marketing approaches are considered in the design process under the static competition condition. the goal of the proposed model is to efficiently respond to the customers’ demands in the presenc...

The following report presents the preliminary results and theoretical backgrounds of a multi-layer evolutionary mechanism. The project aims at developing a mechanism for automated agent design within a pre-designed multi-layer architecture. The core mechanism used in the experiments is a Genetic Programming algorithm working in a specially designed condition-action rules system. There is descri...

in this paper, the distribution network for multi-level supply chain has been studied. products produced in factories are sent to customers through warehouses and distribution centers based on specific demands. warehouses as holding inventory facilities are located close to factories and the distribution centers are placed in the most accessible locations for services near customers. each item ...
