This code (originally written in C++ using the Eclipse CDT) follows the growth of self-replicating interstellar probes on a network of stars.
Each star solves the Lotka-Volterra equations, where each system is coupled to neighbouring systems by inflow/outflow terms for both prey and predators. More information can be found in the accompanying paper:
This code was written in the Eclipse CDT. A standalone Makefile is also available in \src, so when in this directory, typing 'make' should compile the code.
The code is run using the command
> ./lotka_volterra_probes <paramfile>
An example can be found in the paramfiles/ directory. The parameters that define each Lotka-Volterra system can be fixed as constants, sampled from a uniform distribution or sampled from a Gaussian. The parameter file explains how each sampling method is defined/input into the code.
The \plot directory contains Python 2.7 scripts for plotting both the graph generated by the stellar network, and the individual Lotka-Volterra systems within the graph. These were developed using numpy, scipy and matplotlib.
