	UML Tutorial - State Diagrams
		State diagrams are used to describe the behavior of a system.
		State diagrams describe all of the possible states of an object as events occur.
		State diagrams are other combined with other diagrams such as interaction diagrams and activity diagrams.

	Introduction to UML 2 State Machine Diagrams
		A state represents a stage in the behavior pattern of an object, and like UML activity diagrams it is possible to have initial states and final states.
		The capability to indicate method invocations when you enter and exit a state is useful because it enables you to avoid documenting the same method several times on each of the transitions that enter or exit the state, respectively.
		State machine modeling is a dynamic modeling technique, one that focuses on identifying the behavior within your system¾in this case, behavior specific to the instances of a single class.

	Collatz 3n+1 Problem Structure
		The nodes and their edges are based on the state transition diagram which describes the Collatz trajectories.
		It has been suggested that the state transition diagram is less than omnipotent in its support of left descent assemblies and the abstract predecessor tree.
		A bit of the history of the discovery of the identity of the state diagram for the Collatz trajectories in the positive and negative domains is given.

	State Diagram in UML
		State diagrams (also called State Chart diagrams) are used to help the developer better understand any complex/unusual functionalities or business flows of specialized areas of the system.
		History States: A flow may require that the object go into a trance, or wait state, and on the occurrence of a certain event, go back to the state it was in when it went into a wait state—its last active state.
		Create state diagrams when the business logic for a particular flow is very complex, or needs greater understanding by the developer to be coded perfectly.

		STATE 2 -- This state is entered when the user has pressed the button to turn on the light, the light has turned on, and the system is waiting for the user to release the button.
		UML state machine diagrams depict the various states that an object may be in and the transitions between those states.
		A state represents a stage in the behavior pattern of an object, and like UML activity diagrams it is possible to have initial states and final states.

	State Machine Diagram [EA User Guide]
		State Machine representations in UML are based on the Harel State Chart Notation (see the OMG UML Superstructure Specification 2.1.1, section 15, State Machines), and therefore are sometimes referred to as State Charts.
		Composite states and sub-states are both State elements, a composite state being an expanded State element that encloses other State elements, which are then referred to as sub-states.
		A state machine without a context classifier may use triggers that are independent of receptions or operations of a classifier, i.e.

	State diagram - Encyclopedia, History, Geography and Biography
		For a deterministic finite state machine (DFA), nondeterministic finite state machine (NFA), generalized nondeterministic finite state machine (GNFA), or Moore machine, input is signified on each edge, usually near the originating state.
		For a Moore machine the state's output is usually written inside the state's circle, separated from the state's designator with a slash "/".
		The Unified Modeling Language (UML) state diagram is essentially a state diagram with standardised notation that can describe a lot of things, from computer programs to business processes.

	State machine models
		Figure 2.30 shows a state diagram for the Mealy machine derived earlier which produces a 1 as output whenever the sequence 0101 is input.
		Note that a state diagram for a Moore machine is labelled differently from a Mealy machine state diagram; the transitions are labelled only with the inputs which cause the transition, while the states are labelled with the corresponding outputs.
		Comparing the Mealy and Moore state diagrams in Figures 2.30 and 2.31 respectively, it is clear that the diagrams are very similar for states A, B, C and D. State E is a ``new'' state, because the output of 1 must be associated with some state.

	State Diagram
		The state object is a snapshot of an object at a particular point in its life.
		The initial state is the starting state of the object with reference to the behaviour that the diagram explains.
		Each final state is the ending state of the object with reference to the behaviour that the diagram explains.

	Diagram Essentials
		The diagrams described in this document are control flow diagrams (or “flowcharts”), data flow diagrams (or DFDs), context or collaboration diagrams, function decomposition hierarchies, referential or modular decomposition hierarchies, class hierarchy, state diagrams (or “statecharts”), use case diagrams and Venn (set) diagrams.
		State diagrams (or “statecharts”) show relatively high-level transitions that result when the system or program is stimulated by outside events.
		The implementation of state diagrams is often in the form of a finite state machine (or “FSM”).

	State Transition Diagrams
		There is also a capability for concurrent state diagrams, allowing objects to have more than one diagram to describe their behavior.
		State models are ideal for describing the behavior of a single object.
		Their biggest limitation is that they are not good at describing behavior that involved several objects, for these cases use an interaction diagram or an activity diagram.

	Turing Machines (Stanford Encyclopedia of Philosophy)
		The action of a Turing machine is determined completely by (1) the current state of the machine (2) the symbol in the cell currently being scanned by the head and (3) a table of transition rules, which serve as the “program” for the machine.
		The complete state of a Turing machine at any point during a computation may be described by the name of the state that the machine is in, the symbols on the tape, and the cell that is currently being scanned.
		In this formulation, some states are designated as accepting states and when the machine terminates in one of these states, then the computation is successful, otherwise the computation is unsuccessful and any other machines continue in their search for a successful outcome.

	UML Modeling: Creating a State Diagram
		You can use a State diagram when you are working on a real-time process-control application or a subsystem that involves concurrent processing, or when you want to express the behavior of a class over several use cases.
		Identify events and connect states with state transition.
		In a State diagram, an event is represented by an arrow connecting the two states; this is called a State Transition element.

	State Diagrams
		State Diagrams are used to describe the different states and state transitions of an object in the system.
		The key elements of a State Diagram are, of course, the states.
		Since state diagrams model the paths through a system, state diagrams are not tied to the code in a project.

	Hierarchical State Machine Design Pattern
		The states at the higher level in hierarchy perform the common message handling, while the lower level states inherit the commonality from higher level ones and perform the state specific functions.
		A conventional state machine is designed as a two dimensional array with one dimension as the state and the other dimension specifying the message to be handled.
		The state machine determines the message handler to be called by indexing with the current state and the received message.

	java.net: Business Object State Management Using State Machine Compiler
		To use the state machines, as illustrated in Figure 2, we need to bind business objects, which are often implemented as plain old Java objects (POJOs), and wire up the implementations of the action and condition interfaces.
		All of the states and transitions are encapsulated in the generated state machine class.
		Thus, the state machine factory needs to synchronize the current state of the state machine to the business object state, which is not necessarily the start state.

	State Diagram Tips, by Crystal Sloan
		State diagrams show different states of a system (or of a subsystem or object within that system, which are in themselves different systems).
		In a UML state diagram, each possible event that can happen to cause an object or system to change from one state to another is represented by an arrow from the original state to the resulting state, labelled with the name of the event.
		However, in the world of state diagrams, we fortunately do not include this type of "event." We only include the states of the system when it is working in its normal course of operation.
