Webb14 dec. 2024 · streaming algorithm for simulating nearly independent random walks that start at uniformly random vertices. We show that the distribution of $k$-step walks from $b$ vertices chosen uniformly at random can be approximated up to error $\varepsilon$ per walk using $(1/\varepsilon)^{O(k)} 2^{O(k^2)}\cdot b$ words Webb24 sep. 2024 · Simulating a random walk in Python. I am using Python 3. My code below attempts to simulate N steps of a random walk in 3 dimensions. At each step, a random direction is chosen (north, south, east, west, up, down) with 1/6 probability each and a step of size 1 is taken in that direction. The new location is then printed.
