How does this algorithm ensure that wide bridges are built (lets say more than 10 body lengths wide)? Even if the final bridge would be stable the intermediate steps imply a much higher torque.
ants have the ability to lift 5000 times their body weight [1](tiny supermen if you ask me), assuming that helps in building wide bridges and countering the higher torque (during the intermediate steps)
