Abstract: In this paper, the Lax-Wend off difference scheme has been presented for solving the one-dimensional wave equation with integral boundary conditions. First, the given solution domain is discretized and the derivative involving the spatial variable is replaced by the central finite difference approximation of functional values at each grid point by ...

Abstract: The term Sensitivity Analysis (SA), sometimes called the post optimality analysis, refers to an analysis of the effect on the optimal solution of changes in the parameters of problem on the current optimal solution. Simplex method is an iterative procedure which gives the optimal solution to a Linear Programming Problem (LPP) in a finite number of ... Show More
