Abstract
What searching strategies the slime mould adopts when exploring three-dimensional terrains? How optimal are transport routes approximated by the slime mould’s protoplasmic tubes? Do the routes built by slime mould on 3D terrains match real-world transport routes? We conducted laboratory experiments with Nylon terrains of USA and Germany. We used the slime mould to approximate route 20, the longest road in USA, and autobahn 7, the longest national motorway in Europe. We found that slime mould builds longer transport routes on 3D terrains, comparing to flat substrates yet sufficiently approximates man-made transport routes studied. We demonstrated how nutrients placed in destination sites affect performance of slime mould and shown how the slime mould navigates around elevations. In cellular automaton models of the slime mould we shown that the variability of the protoplasmic routes might depends on physiological states of the slime mould.
