    A New NC-Algorithm for Finding a Perfect Matching in d-Regular Bipartite Graphs When d Is Small

    The perfect matching problem for general graphs reduces to the same for regular graphs. Even finding an NC algorithm for the perfect matching problem in cubic (3-regular) or 4-regular graphs will suffice to so...

    Planarity, Determinants, Permanents, and (Unique) Matchings

    We explore the restrictiveness of planarity on the complexity of computing the determinant and the permanent, and show that both problems remain as hard as in the general case, i.e. GapL and #P complete. On the o...

    Dynamic Complexity of Directed Reachability and Other Problems

    We report progress on dynamic complexity of well-known graph problems such as reachability and matching. In this model, edges are dynamically added and deleted and we measure the complexity of each update/quer...

    Property Testing Bounds for Linear and Quadratic Functions via Parity Decision Trees

    In this paper, we study linear and quadratic Boolean functions in the context of property testing. We do this by observing that the query complexity of testing properties of linear and quadratic functions can ...

    On the Complexity of Trial and Error for Constraint Satisfaction Problems

    In a recent work of Bei, Chen and Zhang (STOC 2013), a trial and error model of computing was introduced, and applied to some constraint satisfaction problems. In this model the input is hidden by an oracle wh...

    Reachability is in DynFO

    We consider the dynamic complexity of some central graph problems such as Reachability and Matching and linear algebraic problems such as Rank and Inverse. As elementary change operations we allow insertion and d...
