Importantly, the expressions 1 and 3 that are used to generate shifts in the RW model and noise in Xe are highly influenced by the quality of the generator used, because the generation of random numbers corresponding to three consecutive calls are needed and implies that the sets of possible values generated can be limited by the correlations, the ability to generate 3 calls at least 2 nmeros of equal value is almost null then all possible directions as, may not be generated.
Empirical tests for pseudorandom number generators based on the use of processes or physical models generacoon been successfully used and are considered as complementary to theoretical tests of randomness.

GENERADOR DE NUMEROS PSEUDOALEATORIOS by jose antonio gomez ramirez on Prezi
The last should be undertaken as an independent sequence of random numbers whith the peudoaleatorios probability of occurrence. University Press, c, Third Edition. Contributions to parallel stochastic simulation: Diffusive processes are stochastic processes whose behavior can be simply simulated through the random walker model RW and Langevin dynamics equation DL.
Journal of Computational Physics, Kankaala, Physical Review E 52 In the case of the simulation model DL we used the following parameters: Vilenkin, Ecological Modelling In practice, a computer simulation model RW is to build a system S which particles move with displacements. 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.
Generation and quality checks. L’Ecuyer, Mathematics of Numwros 65 In principle, generation of random numbers pseudoaleatorioe computers is impossible because computers work through determinist nuumeros however, there are determinist generators which generate sequences of numbers that for practical applications could be considered random.

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 Linux operating system based on hardware. 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.
Both models, in the non-interacting free particles approximation, are used to test the quality of the random number generators Janke, ; Passerat-Palmbach, Four-tap shift-register-sequence random-number generators.
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. Vattulainen, New tests of random numbers for simulations in physical systems.
The method is illustrated in the context of the so-called exponential decay process, using some pseudorandom number generators commonly used in physics.
We only show illustratively only two of the most widely PRNGs used.
