- On voit tout de suite que le calendrier comporte quatre journées et qu'il reste 12 matchs à placer.

- Faire tourner le programme de la même façon que précédemment et l'on obtient le résultat suivant :

- Afin que le tableau T5 soit plus facile à exploiter, faire en sorte que pour chaque match, l'équipe locale soit une équipe "Nord"
- Il s'agit en effet qu'une équipe visiteuse d'une région géographique (Nord, par exemple) puisse rencontrer sucessivement deux équipes géographiques locales (Sud, par exemple).

Conclusion :

A partir de l'énoncé du problème, la solution s'organise en trois phases :

1. Constitution des matchs
2. Création des calendriers "mêmes lieux géographiques" et "lieux géographiques différents"
3. Organisation de l'alternance "Locale" / "Visiteuse"

La troisième phase reste à solutionner mais on sait que cela n'est possible qu'en augmentant le nombre de jours du calendrier.

Qu'en pense Constant2001 ?... A suivre !
