drunkards walk

Terms from Artificial Intelligence: humans at the heart of algorithms

A drunkards walk refers to a stochastic process where each step is random, and not based on past history at all. You can create a simple one-dimensional drunkard's walk by tossing a coin then moving forward a step for each head and back a step for each tail. A drunkard's walk is a form of Markov process.
