Thanks!
This is good question. In mentioned techniques ('5 Room Dungeon', '10 Room Dungeon') connection between rooms is for Dungeon Master decision - it can be neigbor rooms, far locations with teleports, etc. But in '5 Room Dungeon Genrator' also exist predefined dungeon variants. I think, may be in future versions of this generator i will add abstract dungeon structure/map generation. And for it already exist column 'Room Mark'.
