👉 Non-recurrent is a mathematical concept in theoretical computer science and automata theory that refers to a state space of a computational model where all states are transient. It's analogous to the word "non-recursive" in programming languages, which means a function or procedure should not repeat its execution indefinitely. In the context of computation, non-recurrent states mean a particular type of memory allocation is never reused, like an array size that cannot be reduced below its initial value after initialization.
