چکیده

The main aim of this contribution is to construct a numerical scheme for solving stochastic time-dependent partial differential equations (PDEs). This has the advantage problems with positive solutions. provides conditions obtaining solutions, which existing Euler–Maruyama method cannot do. In addition, it more accurate than non-standard finite difference (NSFD) method. Theoretically, suggested current NSFD method, and its stability consistency analysis are also shown. applied linear scalar parabolic equation nonlinear auto-catalytic Brusselator model. deficiency in terms accuracy shown by providing different graphs. Many observable occurrences physical world can be traced back certain chemical concentrations. Examining understanding inter-diffusion between concentrations important, especially when they coincide. model gold standard describing relationship other variables systems. A computational code proposed may made available readers upon request convenience.

A Reliable Computational Model For BDI Agents

BDI (Belief, Desire, Intention) is a mature and commonly adopted architecture for intelligent agents. However, the current computational model adopted by BDI has a number of problems with concurrency control, recoverability and predictability. This has hindered the construction of agents having robust and predictable behaviour. To this end, we propose to integrate distributed transactions, a we...

Computational Method for Nonlinear Stochastic Optimal Control

Nonlinear stochastic optimal control problems are treated that are nonlinear in the state dynamics, but are linear in the control. The cost functional is a general function of the state, but the costs are quadratic in the control. The system is subject random fluctuations due to discontinuous Poisson noise that depends on both the state and control, as well as due to discontinuous Gaussian nois...
