Efficient kinetic Monte Carlo simulation

چکیده
This paper concerns Kinetic Monte Carlo (KMC) algorithms that have a singleevent execution time independent of the system size. Two methods are presented— one that combines the use of inverted-list data structures with rejection Monte Carlo and a second that combines inverted lists with the Marsaglia-Norman-Cannon algorithm. The resulting algorithms apply to models with rates that are determined by the local environment but are otherwise arbitrary, time-dependent and spatially heterogeneous. While especially useful for crystal growth simulation, the algorithms are presented from the point of view that KMC is the numerical task of simulating a single realization of a Markov process, allowing application to a broad range of areas where heterogeneous random walks are the dominate simulation cost.

The determination of gyration radius is a strong research for configuration of a Macromolecule. Italso reflects molecular compactness shape. In this work, to characterize the behavior of theprotein, we observe quantities such as the radius of gyration and the average energy. We studiedthe changes of these factors as a function of temperature for Acetylcholine receptor protein in gasphase with n...
متن کاملGeneral kinetic models for vehicular traffic flow and Monte Carlo methods
In this paper we present a general derivation of kinetic models for traffic flows including different kind of interaction rules. We show that most kinetic models previously derived can be cast in the actual formulation. The development of Monte Carlo methods for direct simulation of the kinetic models is considered as an initial step towards realistic and efficient computations of traffic pheno...
متن کاملApplication of Monte Carlo Simulation in the Assessment of European Call Options
In this paper, the pricing of a European call option on the underlying asset is performed by using a Monte Carlo method, one of the powerful simulation methods, where the price development of the asset is simulated and value of the claim is computed in terms of an expected value. The proposed approach, applied in Monte Carlo simulation, is based on the Black-Scholes equation which generally def...
