  Requirements Defined: Requirements Model 1 - The State Table
If there is no requirement related to one of the transitions in the table, there will be no way to transition from one state to the other in the final system.
We constructed a state table and systematically moved through each possible transition to discover almost all of the requirements of the system.
State tables have made complex system analysis problems much simpler and easier to digest for me and I hope that you will find some use for them on one of your projects.

  State transition table - Wikipedia, the free encyclopedia
In Automata Theory, a state transition table is a table describing the transition function T of a finite automaton.
This function governs what state (or states in the case of a nondeterministic finite automaton) the automaton will move to, given an input to the machine.
Given a state diagram of a finite automaton, a state transition table can be derived from it and vice versa.

 Finite state machine - Wikipedia, the free encyclopedia
A transition indicates a state change and is described by a condition that would need to be fulfilled to enable the transition.
Finite state machines are one type of the automata studied in automata theory and the theory of computation.
The next state and output of a FSM is a function of the input and of the current state.

State transition tables are used to represent the operation of the protocol by a number of cooperating state machines each comprising a group of connected, mutually exclusive states.
The execution of any state block appears to be atomic with respect to the execution of any other state block and the transition condition to that state from the previous state is TRUE when execution commences.
On completion of the transition from the previous state to the current state, all exit conditions occurring during the current state (including exit conditions defined for the wildcard state) are evaluated until an exit condition for that state is met.

Table 3 shows that substates 6, 8, and 9 have the same target, the same True and False transition states, and the same True and False routines.
The state transition diagram for the semantic case is shown in Figure 3, and its corresponding sparse table in Table 7.
State machine technique, or finite state automatons, are especially well-suited to applications that involve data-flow tranformations (e.g, parsers or data converters), or ones where control flow is tightly sequenced (e.g., transaction processing applications).

 Tables of Cellular Automaton Properties (1986)
State transition diagram fragments have the general form of cycles fed by trees.
Some finite cellular automata, such as rule 13, are reversible, so that their state transition diagrams contain no transients, and all states are on cycles.
Notice that the results given here and in table 14 for cellular automata on finite lattices with periodic boundary conditions also apply to infinite cellular automata in which only spatially periodic configurations are considered.

The state of the environment, connection, statement, or descriptor usually dictates when functions that use the corresponding type of handle (environment, connection, statement, or descriptor) can be called.
The NS notation in state S11 means that the transitions for the statement are the same as those for a statement in state S1 that creates a result set.
To understand the state transition tables, it is necessary to understand which item (environment, connection, statement, or descriptor) they refer to.

The accepting states are used to distinguish sequences of inputs given to the finite automaton.
The vertices (denoted by single circles) of a transition diagram represent the states of the DFA and the arcs labeled with an input symbol correspond to the transitions.
Since the state 0 is also the accepting state, when all the a's on the tape are read, the DFA is in the accepting state.

 Understand the relationship between mutable service-oriented objects and state machines
The state pattern suggests that when you find yourself with switch statements with a case for each of some finite number of states, you should consider factoring out the behavior for each state into its own class.
To me, the state pattern makes the most sense when the requirements are understood in terms of a state machine in the first place.
So my take on the state pattern is that the state pattern makes sense in the solution, only in those relatively rare cases in which a state machine is used to define the requirements.

A machine-readable endpoint state transition table is interpreted by API routines to manage a state variable maintained for each endpoint.

Given some event and the current state of the endpoint, the array element at the intersection of the row and column is the new state of the endpoint.

A graph of the states and state transitions of a procedure in which states are depicted as bubbles and state transitions are depicted as arcs between the states.
An STT consists of a three part table consisting of: (1) preconditions and their Boolean value assignments; (2) the set of state transitions achieved by satisfying preconditions; and (3) the set of actions taken upon satisfaction of the transition preconditions.
A state transition consists of a Boolean value assignment to the control conditions of the state (the precondition) and the sequence of actions (expressed as methods or block level program slices) taken in the event the preconditions of the transition are satisfied.

 state driven agent design 1
A finite state machine is a device, or a model of a device, which has a finite number of states it can be in at any given time and can operate on input to either make transitions from one state to another or to cause an output or action to take place.
There is no output or action associated with the off state (unless you consider the bulb being off as an action), but when it is in the on state electricity is allowed to flow through the switch and light up your room via the filament in a lightbulb.
Table 2.1 shows an example of the mapping for the states and conditions shown in the previous example.

State reduction techniques also allow you to be sloppy in obtaining the initial finite state machine description.
Two states have equivalent behavior if, for all input combinations, their outputs are the same and they change to the same or equivalent next states.
If we were able to combine states Si and Sj, it would imply that their next state transitions for each input combination must also be equivalent.

This example uses pyparsing to parse out a state transition table, and to generate the associated classes and transition logic a la the State pattern as described in the GOF Design Patterns book.
The State method as implemented in Java, C++, or C# usually begins by defining an abstract class that describes all of the state-specific behaviors, plus a "nextState" method for implementing state transitions.
What is important in implementing a state machine capability is to not only represent the state transitions, but to also be able to associate behavior with the various states.

The purpose of the state diagram (state transition diagram) is to specify stimulus response logic for a system or class of objects.
States may be shown in a generalization specialization hierarchy in which generalization states (superclasses) define the most general, common behavior and specialization states (subclasses) define specialized behavior for an object in the specialization state.
A state diagram and/or a state table displays the sequence and logic of events and conditions triggering actions and possibly triggering the transition to a different state.

When developing state machine engine to control different stages of a user interface, it is important to remember, that user interface (UI) must not only skip from one page to another because FSM instructs to do so, but also to properly update underlying domain model and to stay in sync with it.

A state is a condition that causes a prescribed relationship of inputs to outputs, and of inputs to next states.
A Mealy machine is a state machine where the outputs are a function of both present state and input, as opposed to a Moore machine, in which the outputs are a function only of state.
One of the advantages of a state machine is that it forces the programmer to think of all the cases and, therefore, to extract all the required information from the user.
