Occurring in a non- random manner such that the next state of a system depends only on prior states of the system or the environment. Perfect knowledge of previous states implies perfect knowledge of the next state.
A system is deterministic if it contains no random or noisy inputs or parameters. It is possible to make certain predictions in a deterministic system.
Permitting at most one next move at any step in a computation; changing in a non-random manner, such that the next state of a system depends only on the prior states of the system and/or its environment.
Governed by and predictable in terms of definite laws, such as dynamic equations. Compare nondeterministic.
