Sublinear Fully Distributed Partition with Applications

We present new efficient deterministic and randomized distributed algorithms for decomposing a graph with n nodes into a disjoint set of connected clusters with radius at most k −1 and having O ( n 1+1/ k ) intercluster edges. We show how to implement our algorithms in the distributed model of compu...

Zusammenfassung:We present new efficient deterministic and randomized distributed algorithms for decomposing a graph with n nodes into a disjoint set of connected clusters with radius at most k −1 and having O ( n 1+1/ k ) intercluster edges. We show how to implement our algorithms in the distributed model of computation, i.e., limited message size, which improves the time complexity of previous algorithms (Moran and Snir in Theor. Comput. Sci. 243(1–2):217–241, 2000 ; Awerbuch in J. ACM 32:804–823, 1985 ; Peleg in Distributed Computing: A Locality-Sensitive Approach, 2000 ) from O ( n ) to O ( n 1−1/ k ). We apply our algorithms for constructing low stretch graph spanners and network synchronizers in sublinear deterministic time in the model.
