GitHub Pages hosts your jekyll sites for free under *.github.io. random walk selects a neighbor node with probability 1/d max where d max is the maximum degree of the nodes in a graph. Visualization to illustrate the crazy fact that a random walk on the integer lattice in dimension d <= 2 will return to its starting point with probability 1 whereas a random walk in dimension d >= 3 has a finite probability of never returning. Notice that the example random walk proposal \(Q\) given above satisfies \(Q(y|x)=Q(x|y)\) for all \(x,y\).Any proposal that satisfies this is called “symmetric”. You can think of this like randomly scribbling on a piece of paper.
