      "fr" => "De nombreux problèmes de minimisation de coût consistent à couvrir les sommets ou les arêtes d'un graphe par des sous-graphes vérifiant une certaine propriété. Si le nombre de sous-graphes candidats est une fonction polynomiale de la taille du graphe, l'heuristique gloutonne classique pour le Set Covering, analysée par Chvatal, permet d'approcher l'optimum à rapport logarithmique. Nous étendons ce résultat à des problèmes où le nombre de sous-graphes peut être exponentiel, en utilisant une technique dite "maître-esclave". Les applications concernent des problèmes de télécommunication, de localisation et de conception de circuits électroniques."
      "en" => "Many minimization problems consist in covering vertices or edges of a graph by subgraphs verifying a given property. If the number of candidate subgraphs is a polynomial function depending on the size of the graph, then the classical greedy heuristic for Set Covering, analysed by Chvatal, guarantees a polynomial approximation within a logarithmic ratio. We extend this result to a class of problems with a possible exponential number of subgraphs, by revisiting a technique called "master-slave". Applications are studied for telecommunication, optimal location and VLSI-design."
