### How to deal with sets in NFA?

I have a transition system that I'm converting to an NFA. In the TS, I have a trace of {b} {a, b} {a, b, c}. How would I handle these sets in the NFA? In other words, what would be the path to follow ...

### What's the difference between ioco, uioco and tioco in Model Based Testing?

I'm learning about formal languages and Label Transition Systems (LTSs) and how to test systems using Model-Based Testing. Specifically, the paper Model Based Testing with Labelled Transition Systems ...

### Bisimulation, bisimulation equivalence and simulation equivalence?

I got a little confused with these 3 concepts. Is there a difference between bisimulation and bisimulation equivalence and if yes, then what is it? Also, if we say that the LTS's X and Y are bisimilar,...

### Restriction and re-labeling on CCS

In a process like $$R \stackrel{def}=((a.\bar{b}.0)\setminus\{b\})[a\to b]\mid(\bar{b}.b.0)+\bar{b}.c.0$$ $b$ is restricted to perform on the inner process of RHS $(a.\bar{b}.0)\setminus\{b\}$, ...

### State Machine and State transition Table - Explanation and Creation Of

How do I create a state transition table/array in actual code/pseudo-code? I haven't experienced the "ah-ha" moment yet with the state machine to coding (and I really want to). I've looked at several ...

### CCS synchronization

Within CSS we talk about binary interactions. Does this prevent synchronizing multiple processes in one step? Example: $P_1 ::= a.D$ $P_2 ::= \overline{a}.D$ $P_3 ::= a.D$ Let's consider the ...

### Modeling a sequential circuit as a transition system

I was asked to model the following sequential circuits C1, C2 as transition systems (i.e. identify the output y function and register functions r1, r2, r3) For C2 there appears to be not input x and ...

### Proving weak simulation

I want to prove something but I am not sure if it is the right way to do it. I have two LTS that define different semantics. A=($Q_a,Λ,\to)$, and B=$(Q_b,Λ\cup\{\beta\},\leadsto)$, where $\beta$ is ...

### The Interleaved Transition System for 2 Independent and Concurrent Transition Systems

This question is about Model Checking for Software Formal Verification How do you model the joint behavior of 2 independent and concurrent transition systems? Specifically, given the two independent ...

### What is the difference (if any) between transition systems and finite automata?

is there any difference between transition systems and finite automata? Is it that transition systems consist of both NFA (nondeterministic finite automata) and DFA (deterministic finite automata)?

### Example of Zeno timed automaton

Is there an example of a timed automaton that requires infinite clock precision, in order to be controller so as to avoid a deadlock or bad state? I.e. a transition system that consists of nodes ...

### How to prove that justice isn't enough to produce all naturals?

I'm doing the exercises from the first chapter of the book "Temporal Verification of Reactive Systems Safety" by Manna and Pnueli. However I find very difficult to solve the point c of problem 0.2. ...

### Modelling a basic sequential circuit as a transition system?

I'm going through Dr Joost-Pieter Katoen's slides and stumbled upon this: For some reason I can't quite make out how the transition system relates to the sequential circuit. If I had a question for ...
