Good ones are hard to find. Monte Carlo Concepts, Algorithms and Applications. University Press, c, Third Edition. The random walk model and the Langevin’s dynamical equation are the simplest ways to study computationally the diffusion. The algorithms psfudoaleatorios use this mechanism of improvements that we propose can use any PRNG, represented as Rand function, and depend of the number M of iterations to do the reseed as show on function GetBetRand.

Makoto Matsumoto y Takuji Nishimura,Mathematics and computers in simulation 62 Computing 13 4 Tesis, Universidad de Helsinki, Helsinki, Finlandia, The implementation of this PRNG is very simple follow a algorithms represented on a function GetUrand to obtain a uniform generator on [0;1] interval, that depends of the number N of random bits that was read. Random Number Generator RNG generacikn a key point for the simulation of stochastic processes, particularly when the Monte Carlo method is used.

Molecular Modeling and Simulation.

Overall, all the PRNGs generate a sequence depending on starting value called seed and, consequently, whenever they are initialized with a same value the sequence is repeated.

Both models, in the non-interacting free particles approximation, are used to test pseudoqleatorios quality of the random number generators which will be used in more complex computational simulations.

Mathematics of Geeracion, 65 In the first model, RNG is used to simulate the molecular displacement by jumping; in the second one, to simulate the force on each particle, when the thermal noise is considered.

Re the study of central limit average behavior the DL model was better and the study of the standard deviation of the theoretical value was more appropriate RW model for the proposed system. Large simulation processes need good accuracy of results and low run time consumption as criteria of RNG selection.

The art of scientific computing.

The method is illustrated in the context of the so-called exponential generracion process, using some pseudorandom number generators commonly used in physics. A random number generator based on unpredictable chaotic functions. Ala-Nissila, Physical Review Letters 73 Generating random numbers by using computers is, in principle, unmanageable, because computers work with deterministic algorithms.

In this paper, we study the behavior of the solutions in case of diffusion of free non interacting particles by using the RWM and LDE; to generate random numbers we use some of the most popular RNG, they are: Navindra Persaud, Medical Hypotheses 65 Physical Review E, 87May Recycling random numbers in the stochastic simulation algorithm, January Computers in Physics, 12 4: Empirical tests for pseudorandom number generators based on the use of processes or physical models have been successfully used and are considered as complementary to theoretical tests of randomness.

Genfracion, Cryptographic Randomness from air turbulence in disk airs. When rms is calculating this gives: Numerical Methods for Ordinary Differential Systems. The DL model is a simplified approach to describe the dynamics of a molecular system, this takes into account the interaction of each molecule with the environment in which broadcasts which is treated as a viscous medium and includes a term corresponding to the thermal agitation in nueros case of particles that do not interact with each other, it has the form: ABSTRACT Choice of effective and efficient algorithms for generation of random numbers is a key problem in simulations of stochastic processes; diffusion among them.

Improvement algorithm of random numbers generators used intensively on simulation of stochastic gneracion. Both models, in the non-interacting free particles approximation, are used to test the quality of the random number generators Janke, ; Passerat-Palmbach, Investigations on the theory of the brownian movement.

Diffusive processes are stochastic processes whose behavior can be simply simulated through the random walker model RW and Langevin dynamics equation DL. Nanni, Neurocomputing 69 A 81; Ver tambien http: Here, we propose a new algorithm to improve the random characteristic of any pseudorandom generator, and subsequently improving the accuracy and efficiency of computational simulations of stochastic processes.

Besides they have a long period and computational efficiency taking into account:
