The Euler - Maruyama and Milstein methods are applied to approximate the solution of linearly Langevin equation with multiplicative noise. The exact solution is obtained by applying the Ito's lemma. It is worth mentioning that not always the discretization used to find the solutions of SDEs...

The subject of the present paper is a simplified model for a symmetric bistable system with memory or delay, the reference model, which in the presence of noise exhibits a phenomenon similar to what is known as stochastic resonance. The reference model is given by a one dimensional parametrized...
