WebbThe random order streaming model for computation on graphs has been the focus of much attention recently, resulting in truly sublinear algorithms for several fundamental graph … Webb20 nov. 2024 · In this paper, we study the problem of simulating random walks in the one-pass streaming model. We show space lower bounds for both directed and undirected versions of the problem, and present algorithms that nearly match with the lower bounds. We summarize our results in Section 1.3.
Webb30 nov. 2024 · Using the random.choices function (as you do), this can be achieved using the weights parameter: from random import choices random_direction = choices (population= ['N', 'E', 'S', 'W'], weights= [1, 1, 2, 1], k=1) [0] You could make a single call of choices out of the for loop BTW, since this is a choice with replacement.
