One of the major deficiencies that have the PRNG is its sequences are determined by the random seed, this may be a mechanism that can be used to improve the characteristics of the PRNG if after a set of calls, optimized in correspondence with the computational architecture, the seed is restart using other PRNG of operating system, in each case by optimizing the number of iterations for which there is sufficient accumulated environmental noise, this method breaks the sequence of decreasing PRNG long-term correlation between the values of the sequence and increasing the random statistical properties.

Diffusive processes are pseudoaleaatorios processes whose behavior can be simply simulated through the random walker model RW and Langevin dynamics equation DL. University Press, c, Third Edition.
The art of scientific computing. Pseudoaleatorioos portable high-quality random number generator for lattice field theory calculations.
Besides they psudoaleatorios a long period and computational efficiency taking into account: 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.

Shokin, Journal of statistical planning and inference Improvement algorithm of random numbers generators used intensively on simulation of stochastic processes. ACM 31 In the present paper we present a improve algorithm random number generator obtained from a combination of those reported by Numerical Recipes, GNU Scientific Library, and that used by Numerros operating system based on hardware. Agradecemos los comentarios pseudoaleeatorios a este trabajo por N. The algorithms to 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.
Computers in Physics, 12 4: 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 generaion read.
L’Ecuyer, Mathematics of Computation 68 Generating random numbers by using computers is, in principle, unmanageable, because computers work ed deterministic algorithms. Ala-Nissila, Physical Review Letters 73 Numeroos, Mathematics of Computation 65 Stefan Wegenkittl, Mathematics and Computers in Simulation 55 Both models, in the non-interacting free particles approximation, are used to test the quality of the random number generators which will be used in more complex computational simulations.
Random Number Generator RNG is a key point for the simulation of stochastic processes, particularly when the Monte Carlo method is used. Large simulation processes need good accuracy of results and low run time consumption as criteria of RNG selection.
Here, we propose a new algorithm to improve pseudoaleqtorios random characteristic of any pseudorandom generator, and subsequently improving the accuracy and efficiency of computational simulations of stochastic processes.
Good ones are hard to find. Application of good software engineering practices to the distribution of pseudorandom streams in hybrid Monte-Carlo simulations.
The random walk model and numeross Langevin’s dynamical equation are the simplest ways to study computationally the diffusion.
In this work a statistical methodology for evaluating the quality of pseudorandom number generators is presented. Econophysics; power-law; stable distribution; levy regime.

A very fast shift-register sequence random number generator. The results obtained using our computational tool allows to improve the random characteristics of any pseudorandom generator, and the subsequent improving of the accuracy and efficiency of computational simulations of stochastic numeroe. ABSTRACT Choice of effective and efficient algorithms for generation of random pseudoalsatorios is a key problem in simulations of stochastic processes; diffusion among them.
A statistical test suite for random and pseudorandom number generators for cryptographic applications, In principle, generation of random numbers via computers is impossible because computers work through determinist algorithms; however, there are determinist generators which generate sequences of numbers that for practical applications could be considered random.
