Abstract
Recently, more and more researchers focus on stochastic fractional equations due to their applicability to describe the memory and randomness of many noise systems problems. In the current work, we develop a meshless approach based on moving least square approximation (MLS) to solve stochastic fractional integro-differential equations (SFIDEs). To establish the scheme; we consider the composite Gauss-Legendre integration rule for computing the singular-fractional integral and the Riemann sum for estimating It\(\hat{o}\) integral. We have also compared different basis in terms of CPU time. The error bound of the method is provided. The major accuracy of this approach is that the approximate solutions converge more quickly to the exact solutions by choosing a small number of basis functions and nodes, then the computational cost of the moment matrix is reduced. Several numerical test problems are presented. Comparing the results obtained with other methods confirm the efficiency of the proposed scheme.
