In this regard, a linear combination of Gaussian radial basis functions (GRBF) as approximate mathematical framework is suggested. A set of unknown yet adaptable parameters are modeled in a cost function, representing the trial solution. Differential Evolution (DE) algorithm crossed with Interior Point algorithm (IPA) and Pattern Search (PS) are utilized to find the unknowns. Numerical results based on three special cases of proposed scheme are compared with the exact solution as well as many other numerical and classical approximation methods. Analysis reveals that the proposed scheme is promising in terms of accuracy and conformation to the exact solution.<\/jats:p>","DOI":"10.3233\/jifs-18579","type":"journal-article","created":{"date-parts":[[2019,5,24]],"date-time":"2019-05-24T10:53:30Z","timestamp":1558695210000},"page":"1545-1554","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":7,"title":["Memetic
