Efficient computation of the binary vector that maximizes a rank-deficient quadratic form
The maximization of a full-rank quadratic form over a finite alphabet is NP-hard in both a worst-case sense and an average sense. Interestingly, if the rank of the form is not a ...

Fundamental Domains for Integer Programs with Symmetries
We define a fundamental domain for a linear programming relaxation of a combinatorial integer program which is symmetric under a group action. We then describe a straightforward w...

Distance Coloring
Given a graph G = (V, E), a (d, k)-coloring is a function from the vertices V to colors {1, 2, . . . , k} such that any two vertices within distance d of each other are assigned di...

Concurrent Non-Malleable Commitments
We present a non-malleable commitment scheme that retains its security properties even when concurrently executed a polynomial number of times. That is, a manin-the-middle adversa...
