This booklet is dedicated to Slime mildew Physarum polycephalum, that's a huge unmarried telephone able for dispensed sensing, concurrent info processing, parallel computation and decentralized actuation. the benefit of culturing and experimenting with Physarum makes this slime mildew a fantastic substrate for real-world implementations of unconventional sensing and computing devices
The e-book is a treatise of theoretical and experimental laboratory experiences on sensing and computing houses of slime mildew, and at the improvement of mathematical and logical theories of Physarum habit.
It is proven easy methods to make logical gates and circuits, digital units (memristors, diodes, transistors, wires, chemical and tactile sensors) with the slime mold. The e-book demonstrates easy methods to regulate homes of Physarum computing circuits with practical nano-particles and polymers, to interface the slime mildew with field-programmable arrays, and to take advantage of Physarum as a controller of microbial gas cells.
A particular multi-agent version of slime is proven to serve good as a software program slime mildew able for fixing difficulties of computational geometry and graph optimization. The multiagent version is complemented through mobile automata versions with parallel accelerations. provided mathematical versions encouraged by means of Physarum contain non-quantum implementation of Shor's factorization, structural studying, computation of shortest course tree on dynamic graphs, provide chain community layout, p-adic computing and syllogistic reasoning.
The publication is a different composition of bright and lavishly illustrated essays for you to encourage scientists, engineers and artists to take advantage of traditional phenomena in designs of destiny and emergent computing and sensing units. it's a 'bible' of experimental computing with spatially prolonged dwelling substrates, it spanstopics from biology of slime mildew, to bio-sensing, to unconventional computing units and robotics, non-classical logics and song and arts.

External stimuli such as light and food cause changes in the oscillation frequency. We demonstrate that using these stimuli as logical inputs we can approximate logic gates using these tubes and derive combinational logic circuits by cascading the gates, we can call them frequency gates , with software analysis providing the output of each gate and determining the input of the following gate. Tactile response of the protoplasmic tubes is used for the actuation of two- and four-input logical fluidic gates and memory devices .
