Stochastic
(gcide) | Stochastic \Sto*chas"tic\ (st[-o]*k[a^]s"t[i^]k), a. [Gr.
stochastiko`s, from stocha`zesqai to aim, to guess, fr.
sto`chos mark or aim.]
1. Conjectural; able to conjecture. [Obs.] --Whitefoot.
[1913 Webster]
2. random; chance; involving probability; opposite of
deterministic.
[GG]
3. (Statistics) of or pertaining to a process in which a
series of calculations, selections, or observations are
made, each one being randomly determined as a sample from
a probability distribution.
Note: Where physical phenomena are modelled as a stochastic
process, each subsequent calculation of a series may
depend on the result of the previous calculation, as in
the modelling of the process of diffusion of molecules.
Many series may be calculated, and the results
averaged, to estimate the most likely result. See also
Markov chain.

(wn) | stochastic
adj 1: being or having a random variable; "a stochastic
variable"; "stochastic processes" |
stochastic
(foldoc) | probabilistic
stochastic
Relating to, or governed by, probability. The
behaviour of a probabilistic system cannot be predicted
exactly but the probability of certain behaviours is known.
Such systems may be simulated using pseudorandom numbers.
Evolutionary computation uses probabilistic processes to
generate new (potential) solutions to a problem.
See also deterministic, non-probabilistic.
