Research ArticleOpen accessEvery word in the titleExperimental Comparison Between Evolutionary Algorithm and Barycenter Heuristic for the Bipartite Drawing ProblemZoheir EzzianeThis research investigates the use of intelligent techniques for the bipartite drawing problem (BDP). Due to the combinatorial nature of the solution space, the use of traditional search methods lead to exponential time. Hence, the aim of this paper is to speed up the search time when solving the BDP through the use of Evolutionary Algorithms (EAs) and Barycenter Heuristic … …Journal of Computer Science, Vol. 3, Issue 9 · 30 Sep 2007 · 6,723 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOn the Evolutionary Fitness of Bounded Rationality: Heterogeneous Populations in Antagonistic InteractionsTassos PatokosConventional game theory assumes hyper-rational players, while evolutionary game theory abandons the assumption. This paper studies what happens when agents of both profiles co-exist and get engaged in a series of antagonistic interactions (the Hawk-Dove game). It is shown that if rational agents are perfectly informed as to the type of their opponent, they find it optimal to always be … …American Journal of Applied Sciences, Vol. 2, Issue 13 · 1 Dec 2005 · 8,025 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEOS: Evolutionary Overlay Service in Peer-to-Peer SystemsL. I. Zhijun, Liao MinghongThe peer-to-peer (P2P) systems nowadays can be mainly classified into two categories: structured and structure-less systems based on their overlay organization. The structured systems can achieve determinate efficiency due to their rigorous structure with the cost of losing robustness and vice versa. We provide a semi-structured overlay based on the separation of routing structures and overlay organizations in this paper … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 6,349 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleApplying Evolutionary Computing in Case Retrieval StageNabila Nouaouria-Amri, Med Tayeb LaskriCase Based Reasoning is a problem solving paradigm which is able to retrieve and reuse solutions that have worked for similar situations in the past. Past situations and their solutions are stored in a memory called case base. To find the good experiment in memory is the key of success in the reasoning. To identify adequate experiment in memory constitutes … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 6,742 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHybridization of Neural Learning Algorithms Using Evolutionary and Discrete Gradient ApproachesRanadhir Ghosh, John Yearwood, Moumita Ghosh, Adil BagirovIn this study we investigated a hybrid model based on the Discrete Gradient method and an evolutionary strategy for determining the weights in a feed forward artificial neural network. Also we discuss different variants for hybrid models using the Discrete Gradient method and an evolutionary strategy for determining the weights in a feed forward artificial neural network. The Discrete Gradient … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 6,590 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSolving Multi-Objective Master Production Scheduling Model of Kalak Refinery System Using Hybrid Evolutionary Imperialist Competitive AlgorithmShereen Saleem Sadiq, Adnan Mohsin Abdulazeez, Habibollah HaronThe improvement of operational planning in the field of oil refinery management is becoming increasingly essential and valid. The influential primary factor, among others, is the ever-changing economic climate. The industry must continually assess the potential impacts of variations in the final product demand, price fluctuations, crude oil compositions and even seek out immediate opportunities within the market. The Master … …Journal of Computer Science, Vol. 16, Issue 2 · 12 Feb 2020 · 7,834 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleWEEDS IDENTIFICATION USING EVOLUTIONARY ARTIFICIAL INTELLIGENCE ALGORITHMAhmed M. Tobal, Sahar A. MokhtarIn a world reached a population of six billion humans increasingly demand it for food, feed with a water shortage and the decline of agricultural land and the deterioration of the climate needs 1.5 billion hectares of agricultural land and in case of failure to combat pests needs about 4 billion hectares. Weeds represent 34% of the whole pests while … …Journal of Computer Science, Vol. 10, Issue 8 · 4 Mar 2014 · 7,827 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStructural and Evolutionary Analysis of PARPs in D. discoideumA. Mehadvi Kawal, Hina A. Mir, Chethan Kumar Ramniklal et al.Problem statement: Dictyostelium discoideum, a unicellular eukaryote, exhibits multicellularity upon nutrient starvation, making it a better model for developmental studies and for the study of various signal transduction pathways. The most felicitous point of interest is that many of its genes show high degree of similarity to vertebrate genes. Poly (ADP-ribose) polymerase (PARP), a ubiquitous and abundant nuclear protein, has … …American Journal of Infectious Diseases, Vol. 7, Issue 3 · 3 Nov 2011 · 7,855 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDiscovery of Evolutionary Divergence of Biological Nitrogen Fixation and Photosynthesis: Fine Tuning of Biogenesis of the NifH and the ChlL by a Peptidyl-Prolyl Cis/Trans IsomeraseNara Gavini, Sinny Delacroix, Kelvin Harris Jr., Lakshmi PulakatProblem statement: Despite the structural and functional similarities between the nitrogenase that performs biological nitrogen fixation reaction and the Dark Protochlorphyllide Oxidoreductase (DPOR) that performs chlorophyll-biosynthesis, attempts to substitute nitrogenase-components with DPOR-components have hitherto failed. This investigation was undertaken to test if Chlamydomonas reinhardtii protochlorophyllide (Pchlide) reductase (ChlL) that shares some structural similarity with Nitrogenase Reductase (NifH) could complement the … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 4 · 17 Feb 2012 · 7,620 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Evolutionary Algorithmic Approach based Optimal Web Service Selection for Composition with Quality of ServiceD. Palanikkumar, G. KousalyaProblem statement: Web service is a technology that provides flexibility and interconnection between different distributed applications over the Internet and intranets. When a client request cannot be satisfied by any individual service, existing web services can be combined into a composite web service. When there are a large number of Web services available, it is not easy to find an … …Journal of Computer Science, Vol. 8, Issue 4 · 10 Feb 2012 · 6,766 accessesView PDFCite
