Lattice random walk
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 … Meer weergeven In mathematics, a random walk is a random process that describes a path that consists of a succession of random steps on some mathematical space.
