Agent-based model

An agent-based model (ABM) (also sometimes related to the term multi-agent system or multi-agent simulation) is a class of computational models for simulating the actions and interactions of autonomous agents (both individual or collective entities such as organizations or groups) with a view to assessing their effects on the system as a whole. It combines elements of game theory, complex systems, emergence, computational sociology, multi-agent systems, and evolutionary programming.  more from Wikipedia

Petascale computing

In computing, petascale refers to a computer system capable of reaching performance in excess of one petaflops, i.e. one quadrillion floating point operations per second. The standard benchmark tool is LINPACK and Top500. org is the organisation which tracks the fastest supercomputers. Some uniquely specialized petascale computers do not rank on the Top500 list since they cannot run LINPACK. This makes comparisons to ordinary supercomputers hard.  more from Wikipedia

Space partitioning

In mathematics, space partitioning is the process of dividing a space into two or more disjoint subsets . In other words, space partitioning divides a space into non-overlapping regions. Any point in the space can then be identified to lie in exactly one of the regions.  more from Wikipedia

Exascale computing

Exascale computing refers to computing capabilities beyond the currently existing petascale. If achieved, it would represent a thousandfold increase over that scale. On the basis of a supercomputing conference held in December 2009, Computerworld projected its implementation by 2018..  more from Wikipedia

Stochastic

Stochastic (from the Greek ¿¿¿¿¿¿ for aim or guess) is an adjective that refers to systems whose behavior is intrinsically non-deterministic, sporadic and categorically NOT intermittent. A stochastic process is one whose behavior is non-deterministic, in that a system's subsequent state is determined both by the process's predictable actions and by a random element. However, according to M. Kac and E.  more from Wikipedia

Computer simulation

A computer simulation, a computer model, or a computational model is a computer program, or network of computers, that attempts to simulate an abstract model of a particular system. Computer simulations have become a useful part of mathematical modeling of many natural systems in physics, astrophysics, chemistry and biology, human systems in economics, psychology, social science, and engineering. Simulation of a system is represented as the running of the system's model.  more from Wikipedia
