Burning number of a graph
WebOct 21, 2024 · More precisely, the burning number \(g\) of a graph is defined as the minimum number of time steps needed to achieve the state with all nodes burning. A 3-approximation algorithm for computing \(g\) has been given in [ 2 ], recently a minor improvement to the ratio \(3-2/OPT\) was given in [ 10 ], but still no \((3-\epsilon )\) … WebApr 2, 2024 · The burning number problem on disconnected graphs is harder than on the connected graphs.
