Majority Gates and Circular Computation in Slime Mould

چکیده
Slime mould has been proven to be a fruitful living substrate for implementing a wide range of computing circuits from computational geometry to collision-based logical circuits to robot control. It is apparent, however, that constructing working real-time universal processors from the slime mould is non-trivial task. We explore here similarities between development of slime mould protoplasmic tubes, transportation of cytoplasm inside the tubes and dynamics of propagating patterns in cellular automata. Based on these analogies we will propose computing devices realisable in the living slime mould.

A heterotic, or hybrid, computation implies that two or more substrates of different physical nature are merged into a single device with indistinguishable parts. These hybrid devices then undertake coherent acts on programmable and sensible processing of information. We study the potential of heterotic computers using slime mould acting under the guidance of chemical, mechanical and optical st...
متن کاملDiscovering Boolean Gates in Slime Mould
Slime mould of Physarum polycephalum is a large cell exhibiting rich spatial non-linear electrical characteristics. We exploit the electrical properties of the slime mould to implement logic gates using a flexible hardware platform designed for investigating the electrical properties of a substrate (Mecobo). We apply arbitrary electrical signals to ‘configure’ the slime mould, i.e. change shape...
متن کاملTowards slime mould electrical logic gates with optical coupling
Physarum polycephalum is a macroscopic single celled plasmodial slime mould. We employ plasmodial phototactic responses to construct laboratory prototypes of NOT and NAND logical gates with electrical inputs/outputs and optical coupling; the slime mould plays dual roles of computing device and electrical conductor. Slime mould logical gates are fault tolerant and resettable. The results present...
متن کاملOn hybrid circuits exploiting thermistive properties of slime mould
Slime mould Physarum polycephalum is a single cell visible by the unaided eye. Let the slime mould span two electrodes with a single protoplasmic tube: if the tube is heated to approximately ≈40 °C, the electrical resistance of the protoplasmic tube increases from ≈3 MΩ to ≈10,000 MΩ. The organism's resistance is not proportional nor correlated to the temperature of its environment. Slime mould...

Plasmodium of slime mould Physarum polycephalum is a large single celled organism visible unaided by the eye. This slime mould is capable of optimising the shape of its protoplasmic networks in spatial configurations of attractants and repellents. Such adaptive behaviour can be interpreted as computation. When exposed to attractants and repellents, Physarum changes patterns of its electrical ac...
