A community detection algorithm (for this iteration a form of modularity optimization) is used to help find clusters. The nodes are colored according to these clusters. Eduardo Moreno has been invited to participate in the scientific committee of LAGOS 2013 (Latin American Graphs and Optimization Symposium). Our goal is to understand the tradeoffs between these implementations and how to optimize them. For instance the dictionary elements could be vector of incidence of spanning trees in some fixed graph, and then the linear optimization problem can be solved with a greedy algorithm. Watson Research Center is engaged in basic and applied research in several areas of scientific computing, high-performance computing, algorithms, and optimization. However by doing so we were able to derive linear time algorithm while the 'structural' Interior Point Methods (which use the form of the function to be optimized by deriving an appropriate self-concordant barrier) are not linear time. One such algorithm is the maximum weight matching algorithm in which prices are optimized iteratively to find an assignment that maximizes net benefit in the bipartite graph.

The Hungarian algorithm is used to optimize a graph, represented as a bipartite cost matrix. Posted on: Sunday, May 9th, 2010 The Mathematical Sciences Department at the IBM T.J. As such, the Hungarian algorithm utilizes the bipartite matching algorithm. The new Facebook Graph Search algorithm uses keywords to help users find people, pages, businesses, clubs who share the same interests.

In this paper, we study data-driven and topology-driven implementations of six important graph algorithms on GPUs.
