If a greedy algorithm can be proven to yield the global optimum for a given problem class, it typically becomes the method of choice because it is faster than other optimization methods like dynamic programming. Examples of such greedy algorithms are Kruskal's algorithm and Prim's algorithm for ...
The algorithm Distr, whose running time is \(O(n^2)\), uses Algorithm 6.2 (Greedy Coloring GC), which has complexity \(O(n+m)\) (Kubale 2004). The algorithm GC takes as input a graph G and an arbitrary permutation P of the vertex set of G. GC in Distr legally colors the ...

The well-known greedy coloring is a procedure that takes the vertices of a hypergraph in a given order and colors the current vertex by assigning the smallest positive integer that creates no completely monochromatic edge. The basic property of the greedy algorithm is that a vertex v of color ...

The greedy algorithm for solving the graph vertex coloring problem works as follows: The vertices of the graph are arranged in an arbitrary sequence; The first peak in the series is colored with color 1; Other vertices are colored with the color of the smallest number for which it is valid...

If an algorithm returns a seed set S, it is possible to see the influence coverage on the edge bundling graph by only plotting the influence edges (u, v) if u∈ S. An example of such brushing is shown in Figure 3 below. This figure shows the influence of the number of seeds on ...
