How and where to end this finite state machine program working?
I have written this program from a diagram given to me. I just can't figure out where and how to stop it from running. It keeps asking for inputs forever. Where to add exit command in my program? Any idea?
Thank you.

How to derive the RegEx from the state diagram?
I found a state diagram of a DFA (deterministic finite automaton) with its RegEx in a script, but this diagram is just a sample without any explanations. So I tried to derive the RegEx from the DFA state diagram by myself and got the expression:…

Finite State Automata for a coin change-machine
I'm trying to build a table to describe the behaviour of the FSA for a coin change machine described below.
There is a slot that accepts a 50c coin and 2 buttons that a user can press to get a 20c or 10c coin as change.
As soon as the 50c coin is…

Explaining Computation of a Turing Machine
I am having some trouble interpreting what this Turing machine actually does (i.e., I am uncertain how to explain it in plain English).
I believe I have created the state diagram correctly using the transition table I was given (although not 100%…

UML state diagram: cross-orthogonal region triggers
I'm in the process of getting my head around UML state digrams while analysing the states that one of our customers can have. I'm attempting to use a composite state with orthogonal regions in which one state in one reason is the trigger for at…

UML behavioral state diagram: entry and exit point ownership implications for orthogonal states
In UML (let's take specification 2.4.1), when considering orthogonal composite states, entry and exit points belong either to the (enclosing) composite state or to the region the entry / exit point is drawn in. So which is it?
I cannot find this…
