Physarum Road Planning

 

This page contains selected images and supplementary video recordings of the model particle approximation from the paper:

"Road planning with slime mould. If Physarum built motorways it would route M6/M74 through Newcastle" by Andrew Adamatzky and Jeff Jones, 2009.

Fig. 13 (a) The effect of introducing contamination (simulated salt) into the West Yorkshire urban area under nutrient poor foraging conditions.
t = 2449, 2884, 3189, 3655, 3855 and 4372 scheduler steps.

 

VR Fig. 13 (a) The effect of introducing contamination (simulated salt) into the West Yorkshire urban area under nutrient poor foraging conditions.
Contamination is introduced at approx. 13s with a gradually increasing radius. Contamination is radius shrinks at approx. 19s and reconnection is established.




Fig. 13 (b) The effect of pre-existing contamination at West Yorkshire urban area (radius 37 pixels) on growth and adaptation in a nutrient-rich substrate.
t = 117, 199, 321, 443, 1190, 1539, 2812 and 15000 scheduler steps.

 

Fig. 13 (b) The effect of pre-existing contamination at West Yorkshire urban area (radius 37 pixels) on growth and adaptation in a nutrient-rich substrate.
Contamination radius is gradually reduced at approx 16s until complete removal and network reconnection.
