epädeterministisiä

Epädeterministisiä is a Finnish term that translates to "nondeterministic" in English. It is primarily used in the context of computer science and theoretical computation. A nondeterministic system is one where, for a given input or state, there can be multiple possible next states or outputs. This contrasts with deterministic systems, where each state and input uniquely determines the next state or output.

In theoretical computer science, nondeterminism is often associated with abstract machines like nondeterministic finite automata (NFAs) or nondeterministic Turing machines. These models allow for multiple computational paths to be explored simultaneously or for a "choice" to be made at certain points. While real-world computers are inherently deterministic, the concept of nondeterminism is crucial for understanding the capabilities and limitations of computation, particularly in areas like complexity theory. It helps in classifying problems based on how efficiently they can be solved, even if the actual solution involves simulating nondeterministic behavior. The power of nondeterministic models often lies in their ability to explore a vast number of possibilities in a more concise way than their deterministic counterparts.
