A novel approach for numeric study of 2D biological population model

چکیده
Abstract: In the present paper, the modified cubic B-spline differential quadrature method (MCB-DQM) has been implemented for the numerical computation of two-dimensional biological population model (BPM). The method is based on differential quadrature in which the weighting coefficients are computed by using MCB as a set of basis functions. We present three test problems to confirm the efficiency and accuracy of the method for BPM, which shows that the MCB-DQM solutions are in good agreement with the results obtained by the recent schemes: improved element-free Galerkin method by Zhang et al. and element-free kp-Ritz method by Cheng et al. The order of convergence of MCB-DQM for the solutions of BPM is shown to be quadratic.

متن کاملA new metaheuristic genetic-based placement algorithm for 2D strip packing
Given a container of fixed width, infinite height and a set of rectangular block, the 2D-strip packing problem consists of orthogonally placing all the rectangles such that the height is minimized. The position is subject to confinement of no overlapping of blocks. The problem is a complex NP-hard combinatorial optimization, thus a heuristic based on genetic algorithm is proposed to solve it. I...
