Abstract

The plasmodium of Physarum polycephalum is a large, unicellular and multinuclear organism whose computational ability is attracting a lot of attention in the field of nature-inspired unconventional computing. To test the computational capability of the organism and its utility for future applications, we have implemented the computation of a Voronoi diagram and a collision-free path in an experimental system using Physarum plasmodium. Attractants and repellents for the plasmodium were arranged in the experimental system to induce the plasmodium to form the graphs. The plasmodium solved the complex problem and successfully formedVoronoi diagrams and collision-free paths, demonstrating its computational ability.
