Intractability of Assembly Sequencing: Unit Disks in the Plane
We consider the problem of removing a given disk from a collection of unit disks in the plane. At each step, we allow a disk to be removed by a collision-free translation to infin...

Deconstructing Intractability: A Case Study for Interval Constrained Coloring
The NP-hard Interval Constrained Coloring problem appears in the interpretation of experimental data in biochemistry dealing with protein fragments. Given a set of m integer interv...

A Two-Pronged Attack on the Dragon of Intractability
One approach to tractably finding a solution to an NP-complete optimisation problem is heuristic, where the solution is inexact but quickly found; another approach is to reduce t...

On the Intractability of Inverting Geometric Distortions in Watermarking Schemes
We examine the problem of watermarking schemes robust against geometric distortions from a complexity theoretic point of view. The main results presented are polynomial time reduct...

Parameterized Intractability of Distinguishing Substring Selection
A central question in computational biology is the design of genetic markers to distinguish between two given sets of (DNA) sequences. This question is formalized as the NP-comple...
