On the Descriptive Complexity of Color Coding [PDF]
Color coding is an algorithmic technique used in parameterized complexity theory to detect “small” structures inside graphs. The idea is to derandomize algorithms that first randomly color a graph and then search for an easily-detectable, small color ...

Improved complexity bounds in Wasserstein barycenter problem [PDF]
In this paper, we focus on computational aspects of the Wasserstein barycenter problem. We propose two algorithms to compute Wasserstein barycenters of m discrete measures of size n with accuracy $\e$.

On a Nonsmooth Gauss–Newton Algorithms for Solving Nonlinear Complementarity Problems [PDF]
In this paper, we propose a new version of the generalized damped Gauss–Newton method for solving nonlinear complementarity problems based on the transformation to the nonsmooth equation, which is equivalent to some unconstrained optimization problem ...

A Multi-Dimensional Matrix Product—A Natural Tool for Parameterized Graph Algorithms [PDF]
We introduce the concept of a k-dimensional matrix product D of k matrices A1,…,Ak of sizes n1×n,…,nk×n, respectively, where D[i1,…,ik] is equal to ∑ℓ=1nA1[i1,ℓ]×…×Ak[ik,ℓ].

On the probabilistic min spanning tree Problem [PDF]
International audienceWe study a probabilistic optimization model for min spanning tree, where any vertex v i of the input-graph G(V, E) has some presence probability p i in the final instance G′ ⊂ G that will effectively be optimized.

Data Complexity in Machine Learning and Novel Classification Algorithms [PDF]
This thesis summarizes four of my research projects in machine learning. One of them is on a theoretical challenge of defining and exploring complexity measures for data sets; the others are about new and improved classification algorithms.

Energy-aware lot sizing problem: Complexity analysis and exact algorithms [PDF]
Abstract The single-item lot sizing problem under a periodic energy limitation is considered in this paper. Identical and parallel capacitated machines constitute the production system, each one consuming a certain amount of energy when being switched on, when reserved, and when producing.
