In this paper,we study the concept of split monotone variational inclusion problem with multiple output sets.We propose a new relaxed inertial iterative method with self-adaptive step sizes for approximating the solution of the problem in the framework of Hilbert spaces.Our proposed algorithm does not require the co-coerciveness nor the Lipschitz continuity of the associated single-valued operators.Moreover,some parameters are relaxed to accommodate a larger range of values for the step sizes.Under some mild conditions on the control parameters and without prior knowledge of the operator norms,we obtain strong convergence result for the proposed method.Finally,we apply our result to study certain classes of optimization problems and we present several numerical experiments to demonstrate the implementability of the proposed method.Several of the existing results in the literature could be viewed as special cases of our result in this paper. 展开更多

In this paper,we study the strong convergence of a jump-adapted implicit Milstein method for a class of jump-diffusion stochastic differential equations with non-globally Lipschitz drift coefficients.Compared with the regular methods,the jump-adapted methods can significantly reduce the complexity of higher order methods,which makes them easily implementable for scenario simulation.However,due to the fact that jump-adapted time discretization is path dependent and the stepsize is not uniform,this makes the numerical analysis of jump-adapted methods much more involved,especially in the non-globally Lipschitz setting.We provide a rigorous strong convergence analysis of the considered jump-adapted implicit Milstein method by developing some novel analysis techniques and optimal rate with order one is also successfully recovered.Numerical experiments are carried out to verify the theoretical findings. 展开更多

A class of stochastic differential equations with random jump magnitudes( SDEwRJMs) is investigated. Under nonLipschitz conditions,the convergence of semi-implicit Euler method for SDEwRJMs is studied. The main purpose is to prove that the semi-implicit Euler solutions converge to the true solutions in the mean-square sense. An example is given for illustration. 展开更多
