Abstract. This paper proposes a numerical method to deal with the nonlinear time-fractional integrodifferential
reaction-diffusion equation defined by the Caputo fractional derivative. In the proposed method,
the space variable is eliminated by using finite difference θ-method to enjoy the stability condition. The
method benefits from the radial basis function collocation method, in which the generalized thin plate
splines (GTPS) radial basis functions are used. Therefore, it does not require any struggle to determine
the shape parameter. The obtained results for some numerical examples reveal that the proposed technique
is very effective, convenient and quite accurate to such considered problems.
