A New Approach to Exact Crossing Minimization
The crossing number problem is to find the smallest number of edge crossings necessary when drawing a graph into the plane. Eventhough the problem is NP-hard, we are interested in ...

A branch-and-bound algorithm for the linear ordering problem with cumulative costs
The Linear Ordering Problem with Cumulative Costs is an NP-hard combinatorial optimization problem arising from an application in UMTS mobile-phone communication systems. This pap...

Multilevel algorithms for linear ordering problems
Linear ordering problems are combinatorial optimization problems which deal with the minimization of different functionals in which the graph vertices are mapped onto (1, 2, ..., ...

Multi-prototype Support Vector Machine
We extend multiclass SVM to multiple prototypes per class. For this framework, we give a compact constrained quadratic problem and we suggest an efficient algorithm for its optimi...

DPlace2.0: A stable and efficient analytical placement based on diffusion
Nowadays a placement problem often involves multi-million objects and excessive fixed blockages. We present a new global placement algorithm that scales well to the modern large-s...
