An Alternative LR Algorithm for TAGs
We present a new LR algorithm for treeadjoining grammars. It is an alternative to an existing algorithm that is shown to be incorrect. Furthermore, the new algorithm is much simpl...

Fibonacci numbers, alternating parity sequences and faces of the tridiagonal Birkhoff polytope
We determine the number of alternating parity sequences that are subsequences of an increasing m-tuple of integers. For this and other related counting problems we find formulas th...

Proximal Alternating Minimization and Projection Methods for Nonconvex Problems: An Approach Based on the Kurdyka-Lojasiewicz In
We study the convergence properties of an alternating proximal minimization algorithm for nonconvex structured functions of the type: L(x, y) = f(x)+Q(x, y)+g(y), where f : Rn → ...
