What is the difference between non-determinism and randomness?
Non-deterministic machines allow a finite number of deterministic transitions at each step. For probabilistic machines, these transitions additionally have a probability. This post conveys a …
terminology - Differences and relationships between randomized …
Non-deterministic algorithms are very different from probabilistic algorithms. Probabilistic algorithms are ones using coin tosses, and working "most of the time". As an example, …
complexity theory - What is meant by "solvable by non …
A non-deterministic algorithm is one where the input includes a random choice. Meaning, the input is composed of the nominal input plus a purely random selection -- so the answers differ when …
decidability - Theoretical Computer Science Stack Exchange
Feb 17, 2024 · Intuitively, when a non-deterministic machine branches out, it creates two completely independent "worlds", which may never communicate with each other. The second …
Deterministic vs. Non-Deterministic PDA? - Computer Science …
But in this case, the definition was: "If a PDA has more than one paths going accept state then it is non-deterministic PDA" but what about epsilons? So, Is this an example of Non …
How does a nondeterministic Turing machine work?
The difference between deterministic and non-deterministic Turing machines lies in the transition function. In deterministic Turing machines $\delta$ the transition function is a partial function:
Why is non-determinism a useful concept?
Mar 12, 2014 · In that case, a non-deterministic machine can run both forward and backward in time, while this is not possible in general for a deterministic machine. If we work with total …
finite automata - Why NFA is called Non-deterministic?
Sep 6, 2017 · Why is the non-deterministic finite automaton called non-deterministic while we define the transitions for inputs. Well, even though there are multiple and epsilon transitions, …
computability - What is formal definition of non-deterministic ...
Aug 5, 2023 · 3 I want to understand general method for formally defining non-deterministic algorithm. But all formal definitions I see are related to FSM/Turing-machines. What is the …
Algorithms which are both deterministic and non-deterministic
Here, decisions are made seemingly non-deterministic (in reality, there are advanced heuristics to make these) and back-tracked whenever needed (so that a non-deterministic reasoning …
