Average-Case Analyses of Vickrey Costs
We explore the average-case “Vickrey” cost of structures in a random setting: the Vickrey cost of a shortest path in a complete graph or digraph with random edge weights; the V...

Better Algorithms and Bounds for Directed Maximum Leaf Problems
The Directed Maximum Leaf Out-Branching problem is to find an out-branching (i.e. a rooted oriented spanning tree) in a given digraph with the maximum number of leaves. In this pa...

Performance-Driven Interconnect Global Routing
In this paper, we propose a global routing algorithm for multi-layer building-block layouts. The algorithm is based on successive ripup and rerouting while satisfying edge capacit...

Biobjective evolutionary and heuristic algorithms for intersection of geometric graphs
Wire routing in a VLSI chip often requires minimization of wire-length as well as the number of intersections among multiple nets. Such an optimization problem is computationally ...
