A state diagram for a door that can only be opened and closed. A state diagram is used in computer science and related fields to describe the behavior of systems. State diagrams require that the system is composed of a finite number of states. Sometimes, this is indeed the case, while at other times this is a reasonable abstraction.
A state diagram for a simple example is shown in the figure on the right, using a directed graph to picture the state transitions. The states represent whether a hypothetical stock market is exhibiting a bull market, bear market, or stagnant market trend during a given week. According to the figure, a bull week is followed by another bull week ...
It is possible to draw a state diagram from a state-transition table. A sequence of easy to follow steps is given below: Draw the circles to represent the states given. For each of the states, scan across the corresponding row and draw an arrow to the destination state(s).
The state diagram from Figure 2 is an example of an extended state machine, in which the complete condition of the system (called the extended state) is the combination of a qualitative aspect—the state variable—and the quantitative aspects—the extended state variables. The obvious advantage of extended state machines is flexibility.
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.
The diagram "progress of the computation" shows the three-state busy beaver's "state" (instruction) progress through its computation from start to finish. On the far right is the Turing "complete configuration" (Kleene "situation", Hopcroft–Ullman "instantaneous description") at each step.
The asymptotic availability, i.e. availability over a long period, of the system is equal to the probability that the model is in state 1 or state 2. This is calculated by making a set of linear equations of the state transition and solving the linear system. The matrix is constructed with a row for each state.
An ASM state, represented as a rectangle, corresponds to one state of a regular state diagram or finite-state machine. The Moore type outputs are listed inside the box. State Name. State Name: The name of the state is indicated inside the circle and the circle is placed in the top left corner or the name is placed without the circle. State box
