Algorithm for Elimination of Systems with Sparse Asymmetric Reducible Matrices.
In the paper, an algorithm for finding an optimal or almost optimal permutation for an ordering of elements of a matrix, which is sparse, asymmetric and reducible, is suggested. Using this algorithm we can solve large sparse
