چکیده
What is Physarum? Physarum, or more precisely Physarum polycephalum, is an acellular slime mold, or myxogastrid. Myxogastrids are closely related to the cellular slime molds, or dictyostelids, including the well known Dictyostelium discoideum. Physarum is more distantly related to the protostelids (together these groups are discussed as the eumycetozoans, or ‘true’ slime molds) and very distantly related to other species also called slime molds, for example acrasids.

Timed Transition System Models for Programming Physarum Machines
In the paper, we show that timed transition system models can be used as a high-level model of behavior of Physarum machines. A Physarum machine is a programmable amorphous biological computer experimentally implemented in the vegetative state of Physarum polycephalum. Timed transition system models have been used in our new object-oriented programming language for Physarum polycephalum computing.
متن کاملPteridine biosynthesis and nitric oxide synthase in Physarum polycephalum.
Physarum polycephalum, an acellular slime mould, serves as a model system to study cell-cycle-dependent events since nuclear division is naturally synchronous. This organism was shown to release isoxanthopterin which is structurally related to tetrahydrobiopterin, a cofactor of aromatic amino acid hydroxylases and of nitric oxide synthases (NOSs) (EC 1.14.13.39). Here, we studied Physarum pteri...
متن کاملPhysarum-inspired Network Optimization: A Review
The popular Physarum-inspired Algorithms (PAs) have the potential to solve challenging network optimization problems. However, the existing researches on PAs are still immature and far from being fully recognized. A major reason is that these researches have not been well organized so far. In this paper, we aim to address this issue. First, we introduce Physarum and its intelligence from the bi...
متن کاملA Slime Mold Solver for Linear Programming Problems
Physarum polycephalum (true slime mold) has recently emerged as a fascinating example of biological computation through morphogenesis. Despite being a single cell organism, experiments have observed that through its growth process, the Physarum is able to solve various minimum cost flow problems. This paper analyzes a mathematical model of the Physarum growth dynamics. We show how to encode gen...
متن کاملPhysarum wires: Self-growing self-repairing smart wires made from slime mould
We report experimental laboratory studies on developing conductive pathways, or wires, using protoplasmic tubes of plasmodium of acellular slime mould Physarum polycephalum. Given two pins to be connected by a wire, we place a piece of slime mould on one pin and an attractant on another pin. Physarum propagates towards the attract and thus connects the pins with a protoplasmic tube. A protoplas...
