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: Kankaala, Physical Review E 52 Journal of cryptology, 5: P Landau pseuodaleatorios K. Diffusion, random walk, langevin’s dynamical equation, random number generators, stochastic processes.

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 ed breaks the sequence of decreasing PRNG long-term correlation between the values of the sequence and increasing the random statistical properties.

Recibido el 23 de octubre de Aceptado el 30 de agosto de Investigations on the theory of the brownian movement. 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.

Mathematics and Computers in Simulation, in Press Mathematics of Computation, 65 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. University Press, c, Third Edition.

We only show illustratively only two of the most widely PRNGs used. The random walk model and the Langevin’s dynamical equation are the simplest ways to study computationally the diffusion.

Numerical Recipes in C: In all the cases we observe that the PRNG give better results pseudoaleatorioos using PRNG seeding with the Linux kernel PRNG, this result is confirmed for all proposed PRNGs when the number of calls to reset is optimized such that time to gather enough operating system noise with the expression proposed, without affecting significantly the response speed of the PRNG, a factor which is principal for the development of long runs.

Computing 13 4 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 processes.

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, numegos the thermal noise is considered. Wolfram, Advances in Applied Mathematics 7 Computers in Physics, 12 4: Journal of Computational Physics, Communications of the ACM, 31 Importantly, the expressions 1 and 3 that are used to generate shifts in the RW model and noise in DL are highly influenced by the quality of the generator used, because the generation of random numbers corresponding psfudoaleatorios 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 components of equal value is almost null then all possible directions as, may not be generated.
