This paper uses the L1−norm and the concept of the non-dominated vector, topropose a method to find a well-dispersed subset of non-dominated (WDSND) vectorsof a multi-objective mixed integer linear programming (MOMILP) problem.The proposed method generalizes the proposed approach by Tohidi and Razavyan[Tohidi G., S. Razavyan (2014), determining a well-dispersed subset of non-dominatedvectors of...

Matrix inversion is one of the most significant operations on a matrix. For any non-singular matrix A∈Zn×n, inverse this may contain countless numbers non-integer entries. These entries could be endless floating-point numbers. Storing, transmitting, or operating such an cumbersome, especially when size n large. The only square integer that guaranteed to have as its unimodular U∈Zn×n. With prope...

Suppose that the velocity field is inversely proportional to the radial distance, v = Q 2πr . Such a divergenceless field is natural in two dimensions and is generated by a point sink (or source) of strength Q in an incompressible fluid. This flow field has the remarkable property that the convection term can be absorbed into the diffusion operator by an appropriate shift of the spatial dimensi...
