<< /Prev 213097 Typical information that needs to be computed is so called "quantities of interest" which are of the form E[g(X)], where X is the solution to a stochastic differential equation given by the random model, g is some functional, and E notes the expected value. We consider the problem of the numerical solution of stochastic delay differential equations of Itô form d X(t)=f(X(t),X(t−τ)) d t+g(X(t),X(t−τ)) d W(t), t∈[0,T] and X(t)=Ψ(t) for t∈[−τ,0], with given f,g, Wiener noise W and given τ>0, with a prescribed initial function Ψ.
