Nous avons implémenté une IA Settlers of Catan pour un projet de classe et modifié le code de cette réponse (qui était boguée) pour créer un tableau avec un accès aléatoire en temps constant aux sommets et aux arêtes. C'était un problème amusant, mais le tableau a pris beaucoup de temps, donc au cas où quelqu'un chercherait encore une implémentation simple, voici notre code Python:
