Thiss thesis contains work on reinforced random walks‚ the reconstruction of random sceneriess observed along a random walk path‚ and the length of a longest increasing subsequencee in a random permutation. In this introduction‚ I will survey some of the work inn the area and describe my results. Furthermore I will explain how all three subjects fit intoo the framework of random walks in stochastic surroundings. Section 1 is dedicated to reinforcedd random walks.

We can employ this strategy quite effectively for working with a wide variety of situations Involving probability and random outcomes. We
