Is Max flow NP-complete?

The maximum flow problem with minimum quantities was introduced in [4], where the problem was shown to be weakly NP-complete even on series-parallel graphs and Lagrangean relaxation techniques and heuristics for solving the problem were studied.

Is NP-complete harder than NP?

NP-Complete means that a problem is both NP and NP-Hard. It means that we can verify a solution quickly (NP), but its at least as hard as the hardest problem in NP (NP-Hard). I don’t really know what it means for it to be non-deterministic. Non-determinism is an alternative definition of NP.

Is Ford Fulkerson NP-complete?

Yes, the Ford-Fulkerson algorithm is a pseudopolynomial time algorithm. Its runtime is O(Cm), where C is the sum of the capacities leaving the start node. Since writing out the number C requires O(log C) bits, this runtime is indeed pseudopolynomial but not actually polynomial.

Is Ford Fulkerson greedy?

Ford-Fulkerson algorithm is a greedy approach for calculating the maximum possible flow in a network or a graph.

How many hits does a max flow have?

2000+
Up to 2000+ puffs per disposable.

What does NP-complete stand for?

nondeterministic polynomial-time complete
The name “NP-complete” is short for “nondeterministic polynomial-time complete”. In this name, “nondeterministic” refers to nondeterministic Turing machines, a way of mathematically formalizing the idea of a brute-force search algorithm.

What is meant by maximum flow?

It is defined as the maximum amount of flow that the network would allow to flow from source to sink. Multiple algorithms exist in solving the maximum flow problem.

Does Ford-Fulkerson terminate?

There exists a flow network with real capacities such that Ford-Fulkerson does not terminate. Furthermore, the values of the flows found may converge to some value arbitrarily far from the max flow. Proof. Consider the following graph, where each edge is labeled with its capacity.
