If the machine is in the state S 2 and receives an input of 0, the machine will be in two states at the same time, the states S 1 and S 2. An example of a state-transition table together with the corresponding state diagram for a nondeterministic finite-state machine is given below: This is denoted in a state-transition table by the set of all target states enclosed in a pair of curly braces. This process can be described statistically using Markov Chains.įor a nondeterministic finite-state machine, an input may cause the machine to be in more than one state, hence its non-determinism. In the state diagram, the former is denoted by the arrow looping from S 1 to S 1 labeled with a 1, and the latter is denoted by the arrow from S 1 to S 2 labeled with a 0. Now if the machine is in the state S 1 and receives an input of 0 (first column), the machine will transition to the state S 2. If the machine is in the state S 1 (the first row) and receives an input of 1 (second column), the machine will stay in the state S 1. In the state-transition table, all possible inputs to the finite-state machine are enumerated across the columns of the table, while all possible states are enumerated across the rows. The row/column intersections indicate next states and (optionally) outputs associated with the state transitions. In the first way, one of the dimensions indicates current states, while the other indicates inputs. There are two common ways for arranging them. State-transition tables are typically two-dimensional tables. The single dimension indicates inputs, current states, next states and (optionally) outputs associated with the state transitions. They are much more like truth tables than their two-dimensional form. State-transition tables are sometimes one-dimensional tables, also called characteristic tables. Other ways include a state diagram.Ĭommon forms One-dimension It is essentially a truth table in which the inputs include the current state along with other inputs, and the outputs include the next state along with other outputs.Ī state-transition table is one of many ways to specify a finite-state machine. In automata theory and sequential logic, a state-transition table is a table showing what state (or states in the case of a nondeterministic finite automaton) a finite-state machine will move to, based on the current state and other inputs. Not to be confused with State-transition matrix. ![]()
