On the Complexity of Optimal k-Anonymity: A New Proof Based on Graph Coloring
Privacy is a complex balancing problem between risks and utility of data. K-anonymity, a fundamental model for preserving privacy, guarantees that an item cannot be differentiated from at least k-1 other items.

Minimum weight triangulation is NP-hard [PDF]
A triangulation of a planar point set S is a maximal plane straight-line graph with vertex set S . In the minimum-weight triangulation (MWT) problem, we are looking for a triangulation of a given point set that minimizes the sum of the edge lengths.

Comparing copy-number profiles under multi-copy amplifications and deletions
Background During cancer progression, malignant cells accumulate somatic mutations that can lead to genetic aberrations. In particular, evolutionary events akin to segmental duplications or deletions can alter the copy-number profile (CNP) of a set of ...

Self-concordance is NP-hard [PDF]
We give an elementary proof of a somewhat curious result, namely, that deciding whether a convex function is self-concordant is in general an intractable problem.

Computing the Interleaving Distance is NP-Hard [PDF]
Abstract We show that computing the interleaving distance between two multi-graded persistence modules is NP-hard. More precisely, we show that deciding whether two modules are 1-interleaved is NP-complete, already for bigraded, interval decomposable modules.

Solving NP-SPEC Domains Using ASP [PDF]
NP-SPEC is a language for specifying problems in NP in a declarative way. Despite the fact that the semantics of the language was given by referring to Datalog with circumscription, which is very close to ASP, so far the only existing implementations are

Half-duplex routing is NP-hard [PDF]
Routing is a widespread approach to transfer information from a source node to a destination node in many deployed wireless ad-hoc networks. Today's implemented routing algorithms seek to efficiently find the path/route with the largest Full-Duplex (FD) capacity, which is given by the minimum among the point-to-point link capacities in the path.

Alignment of cluster complexity at network systems [PDF]
This paper considers data management structures and cluster technologies in large-scale networks. Suboptimal network partitioning problems are formulated on the base of complexity index alignment.

Most Tensor Problems Are NP-Hard [PDF]
We prove that multilinear (tensor) analogues of many efficiently computable problems in numerical linear algebra are NP-hard. Our list includes: determining the feasibility of a system of bilinear equations, deciding whether a 3-tensor possesses a given eigenvalue, singular value, or spectral norm; approximating an eigenvalue, eigenvector, singular ...
