WHAT IS IT?
This model simulates quorum sensing in ants while nest site selection and also demonstrates the relation between quorum number and time taken in quorum sensing.
HOW IT WORKS
It works on the concepts of swarm intelligence where each ant observe the number of other ants it has encountered each time when it visits a new nest. and if number of encountered ants exceeds quorum number then all the informed ants switches their recruing mode from forward tandem run to transport
HOW TO USE IT
First set all the parameters eg. population,area,distance and quorum number and then press setup. Finally press GO to start the simulation. You can vary the speed of simulation with help of the timestep slider on top of the screen.
THINGS TO NOTICE
This model uses different colour code for each type of ant
THINGS TO TRY
Try to vary quorum number,distance,area,population and observe it's effect over plotted graph
EXTENDING THE MODEL
This model is beiing extended for multiple nest where selection of a new and best nest site is modelled.
This model has more complidcated code but netlogo was the best platform to implement the idea.
Some models related to foraging are not much related to this model but ant movement in some stages of simulation matches to them.
CREDITS AND REFERENCES
This model is developed by following some important articles on nest site selection.
