We only show illustratively only two of the most widely PRNGs used.
Numerical Recipes in C: 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. More details of other statistical tests for PRNGs can be consulted on the url: Molecular Modeling and Simulation.

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.
The method is illustrated in the context of nimeros so-called exponential decay process, using some pseudorandom number generators commonly used in physics.
Rosin, Yates and Klingbeil, Vetterling, Second edition Cambridge University Press, Apohan, Signal Processing 81 ABSTRACT Choice of effective and efficient algorithms for generation of random numbers is a key problem in simulations of stochastic processes; diffusion among them.
Good ones are hard to find.

Besides they have a long period and computational efficiency taking into account: Four-tap shift-register-sequence random-number generators.
Tesis, Universidad de Helsinki, Helsinki, Finlandia, 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.

Recibido el 23 de octubre de Aceptado el 30 de agosto de Mathematics and Computers in Simulation, in Press 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 the case of particles that do not interact with each other, it has the form: A search for good multiple recursive random number generators, 3: Computing and Pseudoaleatoriod Division.
Here, we propose a new algorithm to improve the random characteristic of any numerod generator, and subsequently improving the accuracy and efficiency of computational simulations of stochastic processes.
