A new algorithm is presented for solving simulation problems which employs minimization and a partial decomposition of the matrix resulting from an alternate diagonal ordering. The technique has been applied to problems in two and three dimensions with good results and examples are given to show the convergence of the method. Examples include heterogeneous, ill-conditioned problems as well as ones with negative and positive co-efficients. 6 refs.
