In the general case, where the maximal degree of a node is 3 or more, the problem is NP-complete. WikiMatrix בשנת 1975, הוא הימר על אונקיה של זהב עם לאונרד אדלמן כי הב...
We confirm that finding an optimal iterative pricing is NP-hard even for acyclic networks with maximum total degree3and with all intrinsic values zero. We design a greedy algorithm which achieves(n1)-approximation for networks with all intrinsic values zero and show that the approximation ration1...

What do you call the property of a list that describes the degree to which it contains duplicates? I believe your function is computing a minimum set cover: Given a set of elements { 1 , 2 , . . . , n } (called the universe) and a collection S of sets whose union equals the un...
In other words, if we only care about testing primality in polynomial time, and not about the degree of the polynomial, then randomness was never needed after all. A third example of the power of randomness comes from the polynomial identity testing (PIT) problem. Here we're given as ...

Finally, we show that our main result applies to networks with constrained in-degree and out-degree, applies to randomized approximation, and even still applies if the ratio bound, instead of being constant, is allowed to be a polynomial function of various aspects of the network topology....

Or responses could be ordered categories, such as the degree of relief: none, a little, some, a lot, or complete. Or responses could be continuous values, such as the time when relief began. Let's run an example using nptrend when responses are 0 or 1. Here we have the variable ...
