The maximum weight connected subgraph problem
Splet1.1 Maximum weight clique vs. maximal cliques. Reporting maximal cliques of a graph is a fundamental problem arising wherever graphs are the natural way to model objects and their interactions. Example applications can be found in network design and analysis, social sciences, or mathematical biology –see the discussion below for illustra- Splet25. mar. 2011 · The maximum weight connected subgraph problem given edge weights is NP-hard apparently, but what I am hoping is that the directed-acyclic nature and the fact …

Splet06. avg. 2016 · Here we consider the Maximum-Weight Connected Subgraph (MWCS) problem for which there are two slightly different formulations. In the most commonly used definition of MWCS only nodes are weighted [ 2, 7 ]. In this paper we consider problem where edges are weighted too [ 8 ]. SpletGiven a positive integer R and a weight for each vertex in a graph, the maximum-weight connected graph problem (MCG) is to find a connected subgraph with R vertices that …

SpletIn computer science, the clique problem is the computational problem of finding cliques (subsets of vertices, all adjacent to each other, also called complete subgraphs) in a graph.It has several different formulations depending on which cliques, and what information about the cliques, should be found. Common formulations of the clique …
