> yeast can find optimal paths in graphs and optimally solve mazes One should be amazed by this but then one shouldn't. As youtube person Masakazu Matsumoto observes: Water and milk can solve the maze faster than the slime mould. 水も迷路を解けます。しかも粘菌よりも速く。 It is a counter-example to the advocacy that the slime mould may be intellectual. [...] Note that this is NOT the evidence for the fact that water and milk are more intellectual than the slime mould, but showing that solving a maze is an easy (i.e. non-NP) problem.
