Low-cost single-layer clock trees with exact zero Elmore delay skew
We give the rst single-layer clock tree construction with exact zero skew according to the Elmore delay model. The previous Linear-Planar-DME method 11 guarantees a planar solutio...

A Non-Linear Schema Theorem for Genetic Algorithms
We generalize Holland's Schema Theorem to the setting that genes are arranged, not necessarily in a linear sequence, but as the nodes in a connected graph. We have experiment...
