In this case the plasmodium behaves in a massively parallel manner and propagates in all possible directions.  ...  If it is assumed that at any time step t of propagation the slime mould can discover and reach not more than p − 1 attractants, then this behaviour can be coded in terms of p-adic numbers.  ...  The point is that in any experiment with the slime mould we deal with attractants which can be placed differently to obtain different topologies and to induce different transitions of the slime mould.  ...
