Я работаю над проектом с роботом под названием boe-bot.
Моя цель - пройти через лабиринт дважды.При первом запуске мой бо-бот пересекает лабиринт, храня пути, взятые в памяти.При втором запуске все пути сохраняются в памяти и удаляются неправильные пути, которые приводят к тупикам, поэтому бо-бот может пройти кратчайший путь до конца лабиринта.
Чтобы сделать это, мне нужно создать правила замены для анализа плохих маршрутов, которые ведут в тупики.
Я создал код на pbasic, но мой код получает ошибки.Есть ли кто-нибудь, кто может помочь мне с этим?
