Simulating random walks in random streams

Webb3 juni 2024 · A random walk model is : Yt = drift + Y (t-1) + shock. My idea which I now realize is missing in my loop, was to use that first value of rw1 and then have the rest of the vector be filled by that same model using the previous value in rw1. So it would have something like : ```rw [i] <- drift + rw [i-1] + shock ´´´ – Santiago Vallejo WebbSince random walks are a powerful tool in algorithm design, it is interesting to study them in the streaming setting. A natural problem is to ﬁnd the space complexity of simulating random walks in graph streams. Das Sarma et al.
