I am reading a file that is filled with hex numbers. I have to identify a particular pattern, say "aaad" (without quotes) from it. Every time I see the pattern, I generate some data to some o...

Is it feasible to use the yield keyword to implement a simple state machine as shown here. To me it looks like the C# compiler has done the hard work for you as it internally implements a state mac...

Does a general proof exist for the equivalence of two (deterministic) finite state machines that always takes finite time? That is, given two FSMs, can you prove that given the same inputs they wil...

I want to write an FSM which starts with an idle state and moves from one state to another based on some event. I am not familiar with coding of FSM and google didn't help. Appreciate if someone co...

I'm using AASM by Rubyist to build a 4-step wizard for an AR object. According to the state of the object, there are different validations that need to be done. What is the smartest way to validate...

In the Stack Overflow podcast #36 (https://blog.stackoverflow.com/2009/01/podcast-36/), this opinion was expressed: Once you understand how easy it is to set up a state machine, you’ll never try to...
