Optimal minimum-delay/area zero-skew clock tree wire-sizing in pseudo-polynomial time
In 21st-Century VLSI design, clocking plays crucial roles for both performance and timing convergence. Due to their non-convex nature, optimal minimum-delay/area zero-skew wire-si...

Approximating minimum bounded degree spanning trees to within one of optimal
In the MINIMUM BOUNDED DEGREE SPANNING TREE problem, we are given an undirected graph with a degree upper bound Bv on each vertex v, and the task is to find a spanning tree of min...
