Connectivity with uncertainty regions given as line segments

Sergio Cabello, David Gajser

For a set of points in the plane and a real number , let be the graph defined on by connecting each pair of points at distance at most . We con…

Minimal normal graph covers

David Gajser, Bojan Mohar

A graph is normal if it admits a clique cover and a stable set cover such that each clique in and each stable set in have a vert…

Simple PTAS's for families of graphs excluding a minor

Sergio Cabello, David Gajser

We show that very simple algorithms based on local search are polynomial-time approximation schemes for Maximum Independent Set, Minimum Vertex Cover and Minimum Dominating Set, wh…

The limit of binomial means of a sequence

David Gajser

For a sequence of real numbers and for a parameter , we define the sequence of its arithmetic means and the sequence of its -bin…

Verifying whether One-Tape Non-Deterministic Turing Machines Run in Time

David Gajser

We discuss the following family of problems, parameterized by integers and : Does a given one-tape non-deterministic -state Turing machine make at most …

Verifying Time Complexity of Deterministic Turing Machines

David Gajser

We show that, for all reasonable functions , we can algorithmically verify whether a given one-tape Turing machine runs in time at most . This is a tight bou…
