yay, ants! A few thoughts: - The overall idea passes the smell test. It makes sense that covering already explored ground is wasteful and walking in a way that minimizes that would be beneficial. - Ants are known to store a vector from their current position to their nest so that they can walk a relatively straight path back home. I wonder if this vector is used to limit the chances of walking back onto a recent path, too? - I learned a while ago that not all ants rely on pheromone trails to food discovered via exploration. For example, seed foraging ants do not rely on food pheromone trails. This is because there's a 1:1 between ant and seed and the location of fallen seeds is fairly randomized. So, a trail would only be misguiding. Modified walking behavior seems related to this - it's all about optimizing rate of food brought back to the nest.
