A Markov chain is any system that observes the Markov property, which means that the conditional probability of being in a future state, given all past states, is dependent only on the present state.

AN INTRODUCTION TO RANDOM WALKS - University of Chicago

A popular random walk model is that of a random walk on a regular lattice, where at each step the location jumps to another site according to some probability distribution. In a simple random walk, the location can only jump to neighboring sites of the lattice, forming a lattice path. In a simple symmetric random walk on a locally finite lattice, the probabilities of the location jumping … WebbThe simple random walk is a simple but very useful model for lots of processes, like stock prices, sizes of populations, or positions of gas particles. (In many modern models, …

WebbSince simple random walk is a process with independent increments, its properties are represented in the most simple way by using the techniques based on characteristic functions. This chapter introduces the necessary mathematical instruments, and then use them to discuss general expressions for the distribution of the walker's displacement … Webb2 Random Walks The probability of making an up move at any step is p, no matter what has happened in the past. The probability of making a down move is 1 − p. This random walk is a special type of random walk where moves are independent of the past, and is called a martingale. If p = 1/2, the random walk is unbiased, whereas if p 6= 1 /2, the ...
