Fixed Parameter Algorithms for one-sided crossing minimization Revisited
We exhibit a small problem kernel for the one-sided crossing minimization problem. This problem plays an important role in graph drawing algorithms based on the Sugiyama layering ...

Minimizing Movement: Fixed-Parameter Tractability
Abstract. We study an extensive class of movement minimization problems which arise from many practical scenarios but so far have little theoretical study. In general, these proble...

Fixed Parameter Polynomial Time Algorithms for Maximum Agreement and Compatible Supertrees
Consider a set of labels L and a set of trees T = {T (1) , T (2) , . . . , T (k) } where each tree T (i) is distinctly leaf-labeled by some subset of L. One fundamental problem is ...

Ubiquitous Parameterization - Invitation to Fixed-Parameter Algorithms
Abstract. Problem parameters are ubiquitous. In every area of computer science, we find all kinds of “special aspects” to the problems encountered. Hence, the study of paramet...

Imbalance Is Fixed Parameter Tractable
In the Imbalance Minimization problem we are given a graph G = (V, E) and an integer b and asked whether there is an ordering v1 . . . vn of V such that the sum of the imbalance of...
