A New Approach for Speeding Up Enumeration Algorithms and Its Application for Matroid Bases
Abstract: We propose a new approach for speeding up enumeration algorithms. The approach does not rely on data structures deeply, instead utilizes analysis of computation time. It ...

A Negative Reinforcement Method for PGA Routing
We present an efficient and effective method for the detailed routing of symmetrical or sea-of-gates FPGA architectures. Instead of breaking the problem into 2-terminal net collec...

Minimizing the stabbing number of matchings, trees, and triangulations
The (axis-parallel) stabbing number of a given set of line segments is the maximum number of segments that can be intersected by any one (axis-parallel) line. We investigate probl...

A 2.5-Factor Approximation Algorithm for the k-MST Problem
The k-MST problem requires finding that subset of at least k vertices of a given graph whose Minimum Spanning Tree has least weight amongst all subsets of at least k vertices. Th...
