Maximal strongly connected cliques in directed graphs: Algorithms and bounds

open access: yes, 2021
International audienceFinding communities in the form of cohesive subgraphs is a fundamental problem in network analysis. In domains that model networks as undirected graphs, communities are generally associated with dense subgraphs, and many community ...

Clearing in financial networks with constrained equal awards

open access: yesInformatika
Objectives. Financial networks with a rule of constrained equal awards for the distribution of the agent’s estate between its creditors are considered. The aim of the study is to develop an algorithm for constructing greatest clearing matrices for such ...

Algorithms for network piecewise-linear programs

open access: yes, 1994
In this paper a subarea of Piecewise-Linear Programming named network Piecewise-Linear Programming (NPLP) is discussed. Initially the problem formulation, main efinitins and related Concepts are presented.

Algorithms for the rainbow vertex coloring problem on graph classes

open access: yes, 2021
Given a vertex-colored graph, we say a path is a rainbow vertex path if all its internal vertices have distinct colors. The graph is rainbow vertex-connected if there is a rainbow vertex path between every pair of its vertices.

About strongly polynomial time algorithms for quadratic optimization over submodular constraints

open access: yes, 1995
We present new strongly polynomial algorithms for special cases of convex separable quadratic minimization over submodular constraints. The main results are: an O(NM log(N2/M)) algorithm for the problem Network defined on a network on M arcs and N nodes;

Local quadratic convergence of polynomial-time interior-point methods for conic optimization problems [PDF]

open access: yes
In this paper, we establish a local quadratic convergence of polynomial-time interior-point methods for general conic optimization problems. The main structural property used in our analysis is the logarithmic homogeneity of self-concordant barrier ...

A Strongly Polynomial Algorithm for Arctic Auctions

open access: yes
Our main contribution is a strongly polynomial algorithm for computing an equilibrium for the Arctic Auction, which is the quasi-linear extension of the linear Fisher market model. We build directly on Orlin's strongly polynomial algorithm for the linear Fisher market (Orlin, 2010).

Maximum constraint satisfaction on diamonds [PDF]

open access: yes
In this paper we study the complexity of the (weighted) maximum constr aint satisfaction problem (Max CSP) over an arbitrary finite domain. In this pro blem, one is given a collection of weighted constraints on overlapping sets of v ariables, and the ...
