Towards a Physarum learning chip [PDF]
Scientific Reports, 2016 AbstractNetworks of protoplasmic tubes of organismPhysarum polycehpalumare macro-scale structures which optimally span multiple food sources to avoid repellents yet maximize coverage of attractants. When data are presented by configurations of attractants and behaviour of the slime mould is tuned by a range of repellents, the organism preforms ...

Convergence of the non-uniform Physarum dynamics [PDF]
Theoretical Computer Science, 2020 Let $c \in \mathbb{Z}^m_{> 0}$, $A \in \mathbb{Z}^{n\times m}$, and $b \in \mathbb{Z}^n$. We show under fairly general conditions that the non-uniform Physarum dynamics \[ \dot{x}_e = a_e(x,t) \left(|q_e| - x_e\right) \] converges to the optimum solution $x^*$ of the weighted basis pursuit problem minimize $c^T x$ subject to $A f = b$ and $|f| \le x$

Robust and emergent Physarum logical-computing
, 2004 There have been many attempts for realization of emergent computing, but the notion of emergent computing is still ambiguous. In an open system, emergence and an error cannot be specified distinctly, because they are dependent on the dis-equilibration ...

Physarum machines for space missions [PDF]
, 2013 A Physarum machine is a programmable amorphous biological computer experimentally implemented in plasmodium Physarum polycephalum. We overview a range of tasks solvable by Physarum machines and speculate on how the Physarum machines could be used in ...

Transcriptomic changes arising during light-induced sporulation in
BMC Genomics, 2010 Background Physarum polycephalum is a free-living amoebozoan protist displaying a complex life cycle, including alternation between single- and multinucleate stages through sporulation, a simple form of cell differentiation.

Programmable reconfiguration of Physarum machines [PDF]
Natural Computing, 2009 Plasmodium of Physarum polycephalum is a large cell capable of solving graph-theoretic, optimization and computational geometry problems due to its unique foraging behavior. Also the plasmodium is unique biological substrate that mimics universal storage modification machines, namely the Kolmogorov-Uspensky machine.

A Unifying Approach to SelfâOrganizing Systems Interacting via Conservation Laws
Advanced Intelligent Discovery, EarlyView.The article develops a unified way to model and analyze selfâorganizing systems whose interactions are constrained by conservation laws. It represents physical/biological/engineered networks as graphs and builds projection operators (from incidence/cycle structure) that enforce those constraints and decompose network variables into constrained versus ...
