WebA random walk on a graph is a process that begins at some vertex, and at each time step moves to another vertex. When the graph is unweighted, the vertex the walk moves to is chosen uniformly at random among the neighbors of the present vertex. When the graph is weighted, it moves to a neighbor with probability proportional to

WebAn adjacency matrix is a way of representing the relationships of these vertices in a 2D array. For unweighted graphs, if there is a connection between vertex i and j, then the value of the cell [i,j] will equal 1, if there is not a connection, it will equal 0. When graphs become weighted, the value of 1 is replaced with the "cost" of the edge ...
