Abstract. We propose an asynchronous protocol for general multiparty computation with perfect security and communication complexity O(n2 |C|k) where n is the number of parties, |C|...
Abstract. Suppose one has access to oracles generating samples from two unknown probability distributions p and q on some N-element set. How many samples does one need to test whet...
We introduce overlap cluster graph modification problems where, other than in most previous work, the clusters of the target graph may overlap. More precisely, the studied graph p...
