Why is non-determinism a useful concept? - Computer Science Stack …
Mar 12, 2014 · Crucially, every outcome the nondeterministic algorithm produces is valid, regardless of which choices the algorithm makes while running. A large number of problems can be …
Differences and relationships between randomized and …
What differences and relationships are between randomized algorithms and nondeterministic algorithms? From Wikipedia A randomized algorithm is an algorithm which employs a degree of …
How does a nondeterministic Turing machine work?
What is differences between deterministic and nondeterministic Turing machines? Different but equivalent models of NDTM. In particular, what is this frequently used phrase "nondeterministically …
decidability - Nondeterministic Turing Machines as deciders, versus NP ...
Feb 17, 2024 · A deterministic Turing machine can simply simulate all the executions of a nondeterministic Turing machine (being careful to interleave executions in the case of recognizers). …
complexity theory - What is meant by "solvable by non deterministic ...
In many textbooks NP problems are defined as: Set of all decision problems solvable by non deterministic algorithms in polynomial time I couldn't understand the part "solvable by non deterministic
Why nondeterminism? - Computer Science Stack Exchange
Some examples include nondeterministic finite automata (NFAs), nondeterministic pushdown automata (PDAs), and nondeterministic Turing machines. Real computers, however, are deterministic (or at …
finite automata - Why NFA is called Non-deterministic? - Computer ...
Sep 6, 2017 · I have this [kind of funny] question in mind. Why is the non-deterministic finite automaton called non-deterministic while we define the transitions for inputs. Well, even though there are multiple...
What is the difference between non-determinism and randomness?
As in the definition of NP, a nondeterministic machine accepts an input if there exists at least one possible accepting computation, and it rejects the input if all computations reject. Randomness …
Deterministic vs. Non-Deterministic PDA? - Computer Science Stack …
What's your source? What they define as non-determinism I know as ambiguity. Non-deterministic automata can be unambiguous! Also, the definition for NFA is definitely not correct. Please cite your …
computability - What is formal definition of non-deterministic ...
Aug 5, 2023 · I have seen its usage in non-formal arguments, so I believe it could be formalized. Another reason is that various simple results on semi-decidable relations seems to be similar to notion of non …
