The current algorithms can compute efficiently the minimum rank of undirected trees. This paper provides an algorithm to compute in polynomial time the minimum rank of directed trees allowing loops.doi:10.48550/arXiv.1204.1444Maguy TrefoisJeanCharles DelvenneMathematics...

This repository contains the solutions and explanations to the algorithm problems on LeetCode. Only medium or above are included. All are written in C++/Python and implemented by myself. The problems attempted multiple times are labelled with hyperlinks.
Quite remarkably, this empirical finding is quantitatively reproduced, for all loop lengths, by our model by fitting its only parameter γ. Moreover, the fitted value of γ correlates quite well with another direct measurement of network directionality, performed by means of a novel algorithm. We...

If a node i∈ VR is deleted from VR in the n-th loop execution of the algorithm, then must hold after the n-th loop execution; so, for arbitrary m > n, node i cannot be inserted into VR again during the m-th loop execution. Proof. For any node i∈ VR, if node i is ...
When Algorithms 2 and 4 are complete, the loop in Algorithm 1 starts, and each iteration updates the time, the satellite’s position (𝐫𝑋rX), the eclipse status (𝜉ξ), the attitude (𝐍𝑋NX), the view factor (F), and the power generation (P) for each side of the CubeSat...
So, does your bridge finding algorithm use only one additional array? In that case it should be faster than the common one, did you measure that? Does it work when parallel edges are allowed? It would be nice to see the actual code to get the answers. → Reply -is-this-fft- 6 ...
so that the while loop executes a small number of times. Given a directed graph of nodes and edges, you are asked to produce an ordering of the edges such that the Bellman-Ford algorithm written by Por Costel should finish after at most two iterations of the while loop(that is, the pro...
