On the Combinatorial Complexity of Approximating Polytopes [PDF]

open access: yesDiscrete and Computational Geometry, 2017
Approximating convex bodies succinctly by convex polytopes is a fundamental problem in discrete geometry. A convex body $K$ of diameter $\mathrm{diam}(K)$ is given in Euclidean $d$-dimensional space, where $d$ is a constant. Given an error parameter $\varepsilon > 0$, the objective is to determine a polytope of minimum combinatorial complexity whose

Simplicity and Complexity in Combinatorial Optimization. [PDF]

open access: yesEntropy (Basel)
Many problems in physics and computer science can be framed in terms of combinatorial optimization. Due to this, it is interesting and important to study theoretical aspects of such optimization. Here, we study connections between Kolmogorov complexity, optima, and optimization.

Combinatorial flexibility problems and their computational complexity

open access: yesElectronic Notes in Discrete Mathematics, 2008
Abstract The concept of flexibility—originated in the context of heat exchanger networks—is associated with a substructure which guarantees the performance of the original structure, in a given range of possible states. We extend this concept to combinatorial optimization problems, and prove several computational complexity results in this new ...

Computational complexity of combinatorial surfaces [PDF]

open access: yesProceedings of the sixth annual symposium on Computational geometry - SCG '90, 1990
We investigate the computational problems associated with combinatorial surfaces. Specifically, we present an algorithm (based on the Brahana-Dehn-Heegaard approach) for transforming the polygonal schema of a closed triangulated surface into its canonical form in O(n log n) time, where n is the total number of vertices, edges and faces. We also give an

Complexity of combinatorial market makers [PDF]

open access: yesProceedings of the 9th ACM conference on Electronic commerce, 2008
We analyze the computational complexity of market maker pricing algorithms for combinatorial prediction markets. We focus on Hanson's popular logarithmic market scoring rule market maker (LMSR). Our goal is to implicitly maintain correct LMSR prices across an exponentially large outcome space.

Combinatorial Laplacian of the Matching Complex [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2002
A striking result of Bouc gives the decomposition of the representation of the symmetric group on the homology of the matching complex into irreducibles that are self-conjugate. We show how the combinatorial Laplacian can be used to give an elegant proof of this result. We also show that the spectrum of the Laplacian is integral.
