Random walk on directed graphRoad coloring60J1060B1505C8137H10A necessary and sufficient condition for a random walk in a finite directed graph subject to a road coloring to be measurable with respect to the driving process is proved to be that the road coloring is synchronizing. The key to ...

1.Random Walk on a Graph(25 Consider the graph shown in Figure1above.There are7nodes,labelled with capital letters and8arcs connecting some of the nodes.On each arc is a numerical weight.Consider a random walk on this graph,where we move randomly from node to node,always going to a ...
1)random walk on graph图上的随机游走过程 1.A novel spectral segmentation method of SAR image is presented based on the multi-step transition probability matrix ofrandom walk on graph.基于图上的随机游走过程,提出了一种新的合成孔径雷达(SAR)图像图谱分割方法。
discrete random walk Xn(as a Markov chain) on G, where the starting point X0is in L.We also assume that the transition probabilities of the corresponding nodes of Kjare the same for allj0 1 2.The simplest case is the one-sided“linear”graph,where L and Kjhave size 1 (see Figure ...
