| Research Abstract |
This research is about computing the probability distribution function of the optimal solution in graphs, which represents network of roads, electric power, computer communication and so on. This study especially focuses on the cases in which the situation changes from time to time like the traffic jams. In the study duration, the following fact was revealed. The probabilistic distribution functions of the stochastic broadcast time and the stochastic shortest time can be computed efficiently if a parameter, treewidth, of a given graph is small.
