A Hierarchical Social Metaheuristic for the Max-Cut Problem
This paper introduces a new social metaheuristic for the Max-Cut problem applied to a weighted undirected graph. This problem consists in finding a partition of the nodes into two ...

Global minimum cuts in surface embedded graphs
We give a deterministic algorithm to find the minimum cut in a surface-embedded graph in near-linear time. Given an undirected graph embedded on an orientable surface of genus g,...

Flow trees for vertex-capacitated networks
Given a graph G = (V, E) with a cost function c(S) ≥ 0 ∀S ⊆ V , we want to represent all possible min-cut values between pairs of vertices i and j. We consider also the spec...

Wide diameters of de Bruijn graphs
Abstract The wide diameter of a graph is an important parameter to measure faulttolerance of interconnection network. This paper proves that for any two vertices in de Bruijn undir...

Approximation Algorithms for Orienteering with Time Windows
Orienteering is the following optimization problem: given an edge-weighted graph (directed or undirected), two nodes s, t and a time limit T, find an s-t walk of total length at ...
