We describe an efficient procedure for sampling representatives from a weighted set such that for any weightings S and T , the probability that the two choose the same sample is equal to the Jaccard similarity between them: Pr[sample(S) = sample(T )] = ∑ x min(S(x), T (x)) ∑ x max(S(x), T (x)) where sample(S) is a pair (x, y) with 0 < y ≤ S(x). The sampling process takes expected computation li...

In this paper we describe the randomized parallel algorithm proposed by Blelloch et al. [BFS12] to compute a Maximal Independent Set (MIS) of a given graph. We implemented their algorithm as well as the fastest sequential algorithm and compared their performance with different input graphs. Furthermore, we compared the number of rounds in both the sequential and parallel algorithms and present ...
