I am interested in Graph Pebbling, and in particular what are the fastest known algorithm is to find the pebbling number of a graph. Also, i am interested whether there are lower limits on the runtime of such algorithms.
I am aware of the paper by Nandor Sieben proposing a graph pebbling algorithm, however it is 10 years old and I am interested whether there have been improvements on this algorithm, therefore my question is:
What is the fastest algorithm calculating the graph pebbling number of a Graph?
