NONDETERMINISM Meaning and
Definition
-
Nondeterminism is a concept often used in computer science, mathematics, and physics that refers to a lack of determinism or predictability in a particular system or process. It is a state where the outcome or behavior of a given situation is not uniquely determined or cannot be precisely predicted, often due to multiple possible outcomes or the presence of random variables.
In computer science, nondeterminism can refer to a specific programming paradigm where the execution of a program can lead to different results each time it is run, even with the same input. This is often seen in programs that involve concurrency, parallelism, or randomization. Nondeterministic algorithms are utilized for solving computational problems, where they explore multiple possible solutions simultaneously, exploiting randomness or probability to arrive at a correct or acceptable answer.
In mathematics, nondeterminism can be observed in non-deterministic finite automata (NDFA) and non-deterministic Turing machines, which are models of computation capable of accepting or recognizing languages or solving decision problems. These models demonstrate that there may exist multiple computational paths or configurations for a given input, and thus the outcome is not uniquely determined.
In physics, nondeterministic systems can be found in the realm of quantum mechanics. According to the Copenhagen interpretation, the behavior of subatomic particles is intrinsically probabilistic, meaning that their precise properties cannot be determined beforehand. This introduces a level of nondeterminism into the microscopic world, contrasting classical deterministic theories.
Etymology of NONDETERMINISM
The word "nondeterminism" is derived from the combination of two root words: "non-" and "determinism".
1. "Non-" is a prefix meaning "not" or "opposite of". It is derived from the Latin word "non" meaning "not".
2. "Determinism" is based on the word "determine", which comes from the Latin word "determinare", meaning "to limit" or "to settle". In philosophy, determinism refers to the belief that every event and action is predetermined or caused by prior events and conditions. It suggests that there is a single outcome or predetermined course for everything.
By combining the prefix "non-" with "determinism", the word "nondeterminism" is formed. It signifies the absence of determinism, or the rejection of the notion that events or actions have a single predetermined outcome.
