WebAbstract. A proper vertex coloring of a graph G is r-dynamic if for each vV (G), at least min {r,d (v)} colors appear in NG (v). In this paper we investigate r-dynamic versions of coloring, list coloring, and paintability. We prove that planar and toroidal graphs are 3-dynamically 10-colorable, and this bound is sharp for toroidal graphs. Web22 de ago. de 2024 · The line in the graphs represents the average value of the selected metric for the specified time period. The boxed area in the graph represents the dynamic threshold of the metric. Point to a graph in the Sparkline Chart widget to view the value of a metric in the form of a tool tip.
