Slime mould computes planar shapes

International Journal of Bio-Inspired Computation (IJBIC), Vol. 4, No. 3, 2012

Abstract: Computing a polygon defining a set of planar points is a classical problem of modern computational geometry. In laboratory experiments, we demonstrate that a concave hull, a connected α-shape without holes, of a finite planar set is approximated by slime mould Physarum polycephalum. We represent planar points with sources of long-distance attractants and short-distance repellents and inoculate a piece of plasmodium outside the dataset. The plasmodium moves towards the data and envelops it by pronounced protoplasmic tubes.
