A self transition is a transition where the initial and the final state are the same. A representative example is a do loop incrementing some counter until it overflows and becomes 0 again. Although the do loop executes the same increment command iteratively, its state space is not a cycle but a line.
Figure 6: UML state diagram of the keyboard state machine with internal transitions. In the absence of entry and exit actions, internal transitions would be identical to self-transitions (transitions in which the target state is the same as the source state).
State diagram for a turnstile A turnstile. An example of a simple mechanism that can be modeled by a state machine is a turnstile. [4] [5] A turnstile, used to control access to subways and amusement park rides, is a gate with three rotating arms at waist height, one across the entryway.
State-transition tables are typically two-dimensional tables. There are two common ways for arranging them. In the first way, one of the dimensions indicates current states, while the other indicates inputs. The row/column intersections indicate next states and (optionally) outputs associated with the state transitions.
A transition without consuming an input symbol is called an ε-transition and is represented in state diagrams by an arrow labeled "ε". ε-transitions provide a convenient way of modeling systems whose current states are not precisely known: i.e., if we are modeling a system and it is not clear whether the current state (after processing some ...
Transition - 1. movement from one State to another in a State machine diagram. The transition is specified by its Trigger-signature [Guard]/Activity 2. a relationship between two states indicating that when a specific event occurs and specific conditions are satisfied an object in the first state will perform certain actions and enter the ...

To investigate the possible state/input/output sequences in an automaton using formal language theory, a machine can be assigned a starting state and a set of accepting states. Then, depending on whether a run starting from the starting state ends in an accepting state, the automaton can be said to accept or reject an input sequence.
