Nondeterminism

Part of speech: noun

Pronunciation: /nɑndəˈtɝmɪnɪzəm/

Definitions

  1. The principle that emphasizes multiple potential outcomes from a set of conditions, where similar inputs can lead to distinct results
  2. A framework in which the same starting parameters may produce diverse consequences, reflecting the variability in systems or computations
  3. A concept highlighting the occurrence of various possible outcomes arising from identical circumstances, showcasing unpredictability in events or processes

Etymology: Nondeterminism is a plain compound, built from the English prefix "non-" and "determinism," so its surprises lie in the parts rather than in any dramatic story. The prefix comes from Old English "nān," meaning "not one" or "none," which itself grew out of "ne" (not) and "ān" (one). That ancestry explains why "non-" works as a simple negator: it means "not" in front of almost anything. "Determinism" is the older half of the pair and carries the real intellectual weight. It describes the view that every event is fixed by prior causes, so that a given state of the world allows only one possible future. Attaching "non-" reverses that view, giving a term for systems or theories in which the same starting conditions can lead to different outcomes. In computing and theoretical science, a nondeterministic process is one whose next step is not fully fixed by its current state, a distinction that makes the word useful well beyond philosophy.
