Random walk models lie at the heart of stochastic dynamics, describing systems in which successive displacements occur according to probability laws. Such processes range from simple, memoryless ...

Markov chains are mathematical models describing sequences of events in which the probability of each future state depends solely on the present state. Random walks constitute a prominent subclass in ...

The last time I looked at random walks, I used them to calculate the value of Pi for Pi Day. But what is a random walk, really? A mathematician will tell you that it's a stochastic process—a path ...
