Ми реалізували Settlers of Catan AI для класового проекту та модифікували код із цієї відповіді (що був помилкою), щоб створити Дошку з постійним випадковим доступом до вершин і країв. Це було цікавою проблемою, але рада займала багато часу, тому у випадку, якщо хтось все ще шукає просту реалізацію, тут є наш Python код:
