[Solved]: Can we test whether two vertices are connected in time linear in the number of nodes?
Problem Detail: Consider the problem: Given an undirected graph and two of its vertices, is there a path between them? I often read that this problem can be solved in linear time in the number of vertices! I am not sure Read More …
[Solved]: Number of clique in random graphs
Problem Detail: There is a family of random graphs $G(n, p)$ with $n$ nodes (due to Gilbert). Each possible edge is independently inserted into $G(n, p)$ with probability $p$. Let $X_k$ be the number of cliques of size $k$ in $G(n, Read More …
[Solved]: Traveling Salesman Problem with Neural Network
Problem Detail: I was curious if there were any new developments in solving the traveling salesman problem using something like a Hopfield recurrent neural network. I feel like I saw something about recent research getting a breakthrough in this, but I Read More …
[Solved]: Does Max-SNP hard imply NP-hard
Problem Detail: I have difficulties understanding the definition of the class Max-SNP (optimization variant of strict NP), thus I have to following basic question: If a problem is known to be Max-SNP hard, does this imply NP-hardness of the problem? Asked Read More …
[Solved]: Can Shortest Job First Scheduling be subject to convoy effect?
Problem Detail: Look at the below table for example : Look at the Non-Preemptive SJF table Suppose if the burst time of process $P_1$ was a very large number compared to $7$, the processes $P_3,P_2$ and $P_4$ have to wait for Read More …
[Solved]: Tasks in which recursion is either the fastest or only way to produce a result
Problem Detail: I’ve just finished studying recursion at university. One thing that stood out for me however was that in both the lectures and in the practical we completed, all the tasks we were asked to do could be performed faster, Read More …
[Solved]: Genetic Algorithm, Neural Network, Deep Learning, Machine Learning Similarities and Applications?
Problem Detail: I am a computer engineering student and trying to get the idea behind all these Artificial Intelligence Concepts and applications. I know little theoretically about machine learning and some high level brief introduction of artificial intelligence as a whole Read More …
[Solved]: Showing NP-hardness of HALF-SAT
Problem Detail: Yesterday I wrote my undergraduate exam in complexity theory. I had to leave off one question, which bugs me since then. Consider: $$ HALF-SAT = { varphi mid varphi text{ is a formula which is satisfied by at least Read More …
[Solved]: Does a graph always have a minimum spanning tree that is binary?
Problem Detail: I have a graph and I need to find a minimum spanning tree to a given graph. What is to be done so that the output obtained is a binary tree? Asked By : Aditya.M Answered By : Juho There is Read More …
