Many experts describe the classic random walk as an integer walk on a number line. With each turn, the random walk actor either advances or retreats by one integer. Random walks are also much more digestible to human learners on a visual level, and can be modeled in two dimensions or thre...

Very roughly speaking, it asserts that on a regular graph of reasonably controlled growth (e.g. polynomial growth), random walks of length concentrate on the ball of radius or so centred at the origin of the random walk. Proof: Let be the graph Laplacian, thus for any , where is ...
The nonstationary time series includetime trends, random walks( also called unit-roots) and seasonalities. Time trends reflect the feature of the time series to grow over time. Seasonalities occur due to change in the time series over different seasons such as each quarter. ...
The objects whose randomness is going to be discussed are binary strings, and our discussion here is so superficial that I will not even distin- guish between finite and infinite ones; see Appendix B for the kind of precision that does enable one to do so. 1. A string x is 1-random ...
