Bonjour,

J'utilise BOOST pour travailler sur un problème de graph mining.

aprés la lécture création des graphes à partir d'un fichier du type:

j'essai de faire une fonction qui retourne la différence entre les arêtes de deux graphes dans un vector, voila la fonction:

Mais lorsque j'essai de compilé le programme (qui se trouve ici http://pastebin.com/xJnZHjgf)
j'ai les erreurs suivantes:

Comment régler ces problémes svp!

[stendhal666]

Tu voudrais bien être un peu plus précis?
Tu compares des itérateurs mais a priori ce sont plutôt les valeurs des arrêtes qui comptent?

En tout cas les messages d'erreur du compilateur n'aident pas beaucoup, le problème est un opérateur - qui est nécessaire quelque part et n'est pas implémenté pour les types que tu utilises. Essaie quand même d'abord de simplifier un peu ton programme, ça pourrait l'éliminer.
En particulier, je crois que tu peux choisir une représentation en forme de set au moment où tu crées ton graphe (avec le spécificateur setS dans le template).
Du coup tu pourrais utiliser set_difference (presque) directement sur edges:

Code :

edge_iterator mbeg, mend, pbeg, pend;
tie(mbeg, mend) = edges(model);
tie(pbeg, pend) = edges(pattern);
std::set_difference etc

.

[mohsenuss91]

Au fait, je voulais commencer par mettre les arrêtes du 1er graphe dans un VECTOR model.. mettre les arrêtes du 2eme graphe dans un autre VECTOR pattern...et après retourné la différence dans un autre VECTOR donc je veux juste retourné les éléments qui se trouve dans model et qui ne se trouve pas dans pattern (et vice versa) .

@stendhal666 : dans mon cas je suis obligé de travailler avec vecS

Alors je proposerais quelque chose comme:

typedef (...) Edge; // à toi de remplir les parenthèses...
typedef (...) edge_iterator;
 
edge_iterator mbeg, mend, pbeg, pend;
tie(mbeg, mend) = edges(g1);
tie(pbeg, pend) = edges(g2);
 
std::vector<Edge> model, pattern;
std::for_each(mbeg, mend, [&](edge_iterator& it) { model.push_back(*it); } // déréférencement de l'itérateur pour avoir la valeur
std::for_each(pbeg, pend, [&](edge_iterator& it) { pattern.push_back(*it); }
 
std::sort(model.begin(), model.end()); // si operator<(Edge, Edge) est défini. Sinon ajouter une fonction de comparaison en troisième paramètre
std::sort(pattern.begin(), pattern.end());
std::set_difference etc // set_difference fonctionne pour n'importe quelle séquence triée.
