Állapítgép

Állapítgép is a Hungarian term that translates to "state machine" in English. It refers to an abstract mathematical model of computation that can be in exactly one of a finite number of states at any given time. The state machine can transition from one state to another in response to external inputs.

The concept of a state machine is fundamental in computer science and is used in various applications. These include designing digital circuits, compiler design, network protocols, and artificial intelligence. State machines are often represented graphically using state diagrams, where circles represent states and arrows represent transitions triggered by inputs.

There are different types of state machines, such as deterministic finite automata (DFA) and non-deterministic finite automata (NFA). A DFA has a unique transition for each state and input symbol, while an NFA can have multiple transitions for the same state and input. Pushdown automata, which include a stack for memory, are another variation.

In essence, an állapítgép provides a structured way to model systems that change behavior over time based on specific events. Its simplicity and clarity make it a powerful tool for understanding and implementing complex sequential logic and behavior. The term is particularly prevalent in Hungarian technical literature and discussions related to theoretical computer science and system design.
