The digital bacterial-based minesweeper
We created a 2D spatio-temporal model of the Colisweeper bacterial game to evaluate our network, validate the design and get some insights of how we can improve our system. Essentially we study the diffusion of OHHL in a hexagonal grid setup with mine and non-mine colonies. For the simulation, we used COMSOL Multiphysics. Most of the model parameters are derived from literature supported by experimental evidence, and very few of them are fitted. It is important to highlight that the model and the experimentation need to be viewed in close interplay. Based on this premise we generate data from experiments to validate the model, but also use to model to predict the behaviour of our system and help further experimental designs.
-
Level of GFP expression, after 11 hours of incubation, depending on the number of mine cells surrounding a colony. On the left is shown the experimental result (fluorescence) and on the right the simulation results are displayed, corresponding to concentration of GFP (mol/m3). Mine colonies are delimited in green.
-
OHHL Diffusion concentration gradient after 24 hours.
