;; Two Nest Updates
;; X  at the beginning create two nests with two different populations
;; X  each ant will need to know which nest it is from
;; X  ants see other nests as food sources
;; X  at each food source, ants return to the closest nest and join that nest with a certain probability
;; X  keep track of amount of food in each nest. Ants can only take food if there is food to take
;; X  set food source and nest locations using absolute coordinates
;; X  orient ants towards food source or nest they returned from

;; Realism Updates
;; X  food sources have rate of food production. ants bring back constant amount of food if they can
;; X  nest consumption proportional to population
;; X  nest and food sources have max amount of food they can store
;;    lets get everything in the right units
;;      X  30mx30m area
;;      X  ants move @ 1cm/s -> each tick is 100 seconds, should reference everything else from this (mainly food production), nothing should be larger than one patch for the most part
;;      X  maximum trail length possible to maintain should be about 25m (sandor data, he probably got that figure from somewhere else)
;;      X  make nest maximum proportional to the amount of nests in the ant and the load per ant (from lecheval)
;; X  make it so that ants will return from other nest empty-handed if there's no food there instead of continuing on to search at other food sources and then joining the new nest
;;    ants need to return to a nest following the same trails they used to get there --> nest stack?
;;       if an ant passes through/near a nest, add that to the stack
;;       on the return trip, the ants pops off the stack and goes to that nest until it gets home


;; Quality of life updates
;; X  food and nest labels for ease of use
;; X  trail strength monitor (ants on trail / distance)
;; X  get food source with the strongest and weakest trails and monitor
;;    moving averages?
;; >  network efficiency plot
;; >      all vertices
;; >      nests only
;; >  network robustness plot                       Seems it would be best to use ready-made functions and do all of this in R or python
;; >      all vertices                                 Would be good to figure out how we convert the data we have into a graph though
;; >      nests only


;; Experiment Updates
;; X  Function to set a food source's production rate by number
;; X  Function to report a food source's production rate by number
;; X  Capability to set a start and stop time for exclusion and make that exclusion happen
;; X  add directionality to internest strengths
;; X  Need to make it so that the strength between a nest and a food source is only counting ants that will actually return to that food source
;;     X Trail strengths sum across all nests, we have to interpret which nest they are actually going to / coming from
;;     X Need a function that returns the distance from a point to the nearest nest
;; X  When excluding the weakest trail, it needs to be a trail that is actually being used
;;     X Need to be able to set a threshold for "in use", which should clearly be 2.5 ants / m <--> "10 for 400"

;; Major overhaul, everything that can be is list-based now.
;;    It does seem to run slower but it is significantly easier to modify things now

## WHAT IS IT?

In this project, a colony of ants forages for food. Though each ant follows a set of simple rules, the colony as a whole acts in a sophisticated way.

## HOW IT WORKS

When an ant finds a piece of food, it carries the food back to the nest, dropping a chemical as it moves. When other ants "sniff" the chemical, they follow the chemical toward the food. As more ants carry food to the nest, they reinforce the chemical trail.

## HOW TO USE IT

Click the SETUP button to set up the ant nest (in violet, at center) and three piles of food. Click the GO button to start the simulation. The chemical is shown in a green-to-white gradient.

The EVAPORATION-RATE slider controls the evaporation rate of the chemical. The DIFFUSION-RATE slider controls the diffusion rate of the chemical.

If you want to change the number of ants, move the POPULATION slider before pressing SETUP.

## THINGS TO NOTICE

The ant colony generally exploits the food source in order, starting with the food closest to the nest, and finishing with the food most distant from the nest. It is more difficult for the ants to form a stable trail to the more distant food, since the chemical trail has more time to evaporate and diffuse before being reinforced.

Once the colony finishes collecting the closest food, the chemical trail to that food naturally disappears, freeing up ants to help collect the other food sources. The more distant food sources require a larger "critical number" of ants to form a stable trail.

The consumption of the food is shown in a plot.  The line colors in the plot match the colors of the food piles.

## EXTENDING THE MODEL

Try different placements for the food sources. What happens if two food sources are equidistant from the nest? When that happens in the real world, ant colonies typically exploit one source then the other (not at the same time).

In this project, the ants use a "trick" to find their way back to the nest: they follow the "nest scent." Real ants use a variety of different approaches to find their way back to the nest. Try to implement some alternative strategies.

The ants only respond to chemical levels between 0.05 and 2.  The lower limit is used so the ants aren't infinitely sensitive.  Try removing the upper limit.  What happens?  Why?

In the `uphill-chemical` procedure, the ant "follows the gradient" of the chemical. That is, it "sniffs" in three directions, then turns in the direction where the chemical is strongest. You might want to try variants of the `uphill-chemical` procedure, changing the number and placement of "ant sniffs."

## NETLOGO FEATURES

The built-in `diffuse` primitive lets us diffuse the chemical easily without complicated code.

The primitive `patch-right-and-ahead` is used to make the ants smell in different directions without actually turning.
