Fractional Step Runge-Kutta Methods for the Resolution of Two Dimensional Time Dependent Coefficientl provide totally discrete algorithms with low computational cost and high order of accuracy in time. We will show the efficiency of such methods, in combination with upwind difference schemes on special meshes, to integrate numerically singularly perturbed evolutionary convection-diffuusion problems.

Variable Stepsizes in Symmetric Linear Multistep Methodsetric linear multistep methods especially designed for second order differential equations can integrate very efficiently periodic or quasiperiodic orbits till long times. A study will be given on what happens when variable stepsizes are considered so as to deal with highly eccentric orbits.

Inexact Newton Methods and Mixed Nonlinear Complementary Problemsethod applied to a particular system of nonlinear equations.We have applied this inexact interior point algorithm for the solution of some nonlinear complementary problems. We provide numerical results in both sequential and parallel implementations.

Sensitivity Analysis of the Expected Accumulated Reward Using Uniformization and IRK3 Methodshe third order implicit Runge-Kutta method. After providing a new way of writing the system of equations to be solved, we applythi s method with a stepsize choice different from the classical one in order to accelerate the algorithm execution. Finally, we compare the time complexity of both of the methods on a numerical example.

Skew-Circulant Preconditioners for Systems of LMF-Based ODE Codestioned or singular even when the given system is well-conditioned. In this paper, we propose a nonsingular skew-circulant preconditioner for systems of LMF-based ODE codes. Numerical results are given to illustrate the effectiveness of our method.
