Editing Random walk (section)

==== Heterogeneous generalization ====
{{Main|Heterogeneous random walk in one dimension}}
The heterogeneous random walk draws in each time step a random number that determines the local jumping probabilities and then a random number that determines the actual jump direction. The main question is the probability of staying in each of the various sites after <math>t</math> jumps, and in the limit of this probability when <math>t</math> is very large.
