Abstract

The giant unicellular slime mould Physarum polycephalum forms an extended network of stands (veins) that provide for an effective intracellular transportation system, which coarsens in time. The network coarsening was investigated numerically using an agent-based model and the results were compared to experimental observations. The coarsening process of both numerical and experimental networks was characterised by analyses of the kinetics of coarsening, of the distributions of geometric network parameters (as, for instance, the lengths and widths of vein segments) and of network topologies.
