Efficient Exact Stochastic Simulation of Chemical Systems with Many Species and Many Channels

There are two fundamental ways to view coupled systems of chemical equations: as continuous, represented by differential equations whose variables are concentrations, or as discrete, represented by stochastic processes whose variables are numbers of molecules. Although the former is by far more common, systems with very small numbers of molecules are important in some applications (e.g., in sma...

Efficient simulation of one-dimensional quantum many-body systems.

We present a numerical method to simulate the time evolution, according to a generic Hamiltonian made of local interactions, of quantum spin chains and systems alike. The efficiency of the scheme depends on the amount of entanglement involved in the simulated evolution. Numerical analysis indicates that this method can be used, for instance, to efficiently compute time-dependent properties of l...

Efficient parallelization of the genetic algorithm solution of traveling salesman problem on multi-core and many-core systems

Efficient parallelization of genetic algorithms (GAs) on state-of-the-art multi-threading or many-threading platforms is a challenge due to the difficulty of schedulation of hardware resources regarding the concurrency of threads. In this paper, for resolving the problem, a novel method is proposed, which parallelizes the GA by designing three concurrent kernels, each of which running some depe...

Exact stochastic simulation of coupled chemical reactions

There are two formalisms for mathematically describing the time behavior of a spatially homogeneous chemical system: The deterministic approach regards the time evolution as a continuous, wholly predictable process which is governed by a set of coupled, ordinary differential equations (the “reaction-rate equations”); the stochastic approach regards the time evolution as a kind of random-walk pr...

Efficient Simulation of Fluid Queues with Many Sources

In this paper we study the rare event of overflow in a Markov fluid queue with finite buffer and many input sources. The probability of this rare event will be estimated by simulations. We present a highly efficient importance sampling procedure to speed up the simulations. The implemented change of meausure is suggested after a large deviations analysis of the overflow probability. This analys...
