This problem is NP-hard and finds …
WebWe follow this trend by solving the problem in polynomial time for graphs (modeling the underlying network) of bounded pathwidth and for graphs of bounded carvingwidth, which represent two main graph classes frequently studied for hard problems such as p-Coverage. Actually, we first show that the problem is polynomially solvable for graphs of ... Web122 rows · 2493. Divide Nodes Into the Maximum Number of Groups. 37.0%. Hard. 2497.

WebMar 21, 2024 · A Graph is a non-linear data structure consisting of vertices and edges. The vertices are sometimes also referred to as nodes and the edges are lines or arcs that connect any two nodes in the graph. More formally a Graph is composed of a set of vertices ( V ) and a set of edges ( E ). The graph is denoted by G (E, V). WebFinally, we show that the problem of computing the total weak Roman domination number of a graph is NP-hard. Given a graph G = ( V , E ) , a function f : V → { 0 , 1 , 2 , ⋯ } is said to be a total dominating function if ∑ u ∈ N ( v ) f ( u ) > 0 for every v ∈ V , where N ( v ) denotes the open neighbourhood of v. ...
WebFeb 2, 2024 · NP-complete problems are the hardest problems in the NP set. A decision problem L is NP-complete if: 1) L is in NP (Any given solution for NP-complete problems can be verified quickly, but there is no efficient known solution). 2) Every problem in NP is reducible to L in polynomial time (Reduction is defined below). A problem is NP-Hard if …
