👉 Semidead is a concept in computer science and mathematics that refers to an event or process that occurs at least once, but not necessarily infinitely often. It's similar to a finite state machine, but instead of having only one output, it has two outputs - "active" and "inactive". In the context of semideads, we can think of them as "waiting" for something to happen, yet they are not actually "dead", since they're still active.
