## WHAT IS IT?
This model explores the stability of predator-prey ecosystems. Such a system is called unstable if it tends to result in extinction for one or more species involved. In contrast, a system is stable if it tends to maintain itself over time, despite fluctuations in population sizes.
## HOW IT WORKS
There are two main variations to this model.
In the first variation, wolves and sheep wander randomly around the landscape, while the wolves look for sheep to prey on. Each step costs the wolves energy, and they must eat sheep in order to replenish their energy - when they run out of energy they die. To allow the population to continue, each wolf or sheep has a fixed probability of reproducing at each time step. This variation produces interesting population dynamics, but is ultimately unstable.
The second variation includes grass (green) in addition to wolves and sheep. The behavior of the wolves is identical to the first variation, however this time the sheep must eat grass in order to maintain their energy - when they run out of energy they die. Once grass is eaten it will only regrow after a fixed amount of time. This variation is more complex than the first, but it is generally stable.
The construction of this model is described in two papers by Wilensky &amp; Reisman referenced below.
## HOW TO USE IT
1. Set the GRASS? switch to TRUE to include grass in the model, or to FALSE to only include wolves (red) and sheep (white).
2. Adjust the slider parameters (see below), or use the default settings.
3. Press the SETUP button.
4. Press the GO button to begin the simulation.
5. Look at the monitors to see the current population sizes
6. Look at the POPULATIONS plot to watch the populations fluctuate over time
Parameters:
INITIAL-NUMBER-SHEEP: The initial size of sheep population
INITIAL-NUMBER-WOLVES: The initial size of wolf population
SHEEP-GAIN-FROM-FOOD: The amount of energy sheep get for every grass patch eaten
WOLF-GAIN-FROM-FOOD: The amount of energy wolves get for every sheep eaten
SHEEP-REPRODUCE: The probability of a sheep reproducing at each time step
WOLF-REPRODUCE: The probability of a wolf reproducing at each time step
GRASS?: Whether or not to include grass in the model
GRASS-REGROWTH-TIME: How long it takes for grass to regrow once it is eaten
SHOW-ENERGY?: Whether or not to show the energy of each animal as a number
Notes:
- one unit of energy is deducted for every step a wolf takes
- when grass is included, one unit of energy is deducted for every step a sheep takes
## THINGS TO NOTICE
When grass is not included, watch as the sheep and wolf populations fluctuate. Notice that increases and decreases in the sizes of each population are related. In what way are they related? What eventually happens?
Once grass is added, notice the green line added to the population plot representing fluctuations in the amount of grass. How do the sizes of the three populations appear to relate now? What is the explanation for this?
Why do you suppose that some variations of the model might be stable while others are not?
## THINGS TO TRY
Try adjusting the parameters under various settings. How sensitive is the stability of the model to the particular parameters?
Can you find any parameters that generate a stable ecosystem that includes only wolves and sheep?
Try setting GRASS? to TRUE, but setting INITIAL-NUMBER-WOLVES to 0. This gives a stable ecosystem with only sheep and grass. Why might this be stable while the variation with only sheep and wolves is not?
Notice that under stable settings, the populations tend to fluctuate at a predictable pace. Can you find any parameters that will speed this up or slow it down?
Try changing the reproduction rules -- for example, what would happen if reproduction depended on energy rather than being determined by a fixed probability?
## EXTENDING THE MODEL
There are a number ways to alter the model so that it will be stable with only wolves and sheep (no grass). Some will require new elements to be coded in or existing behaviors to be changed. Can you develop such a version?
## NETLOGO FEATURES
Note the use of breeds to model two different kinds of &quot;turtles&quot;: wolves and sheep. Note the use of patches to model grass.
Note use of the ONE-OF agentset reporter to select a random sheep to be eaten by a wolf.
## RELATED MODELS
Look at Rabbits Grass Weeds for another model of interacting populations with different rules.

*
* In addition to Lo-Dash methods, wrappers also have the following `Array` methods:
* `concat`, `join`, `pop`, `push`, `reverse`, `shift`, `slice`, `sort`, `splice`,
* and `unshift`
*
* Chaining is supported in custom builds as long as the `value` method is
* implicitly or explicitly included in the build.
*
* The chainable wrapper functions are:
* `after`, `assign`, `bind`, `bindAll`, `bindKey`, `chain`, `compact`,
* `compose`, `concat`, `countBy`, `create`, `createCallback`, `curry`,
* `debounce`, `defaults`, `defer`, `delay`, `difference`, `filter`, `flatten`,
* `forEach`, `forEachRight`, `forIn`, `forInRight`, `forOwn`, `forOwnRight`,
* `functions`, `groupBy`, `indexBy`, `initial`, `intersection`, `invert`,
* `invoke`, `keys`, `map`, `max`, `memoize`, `merge`, `min`, `object`, `omit`,
* `once`, `pairs`, `partial`, `partialRight`, `pick`, `pluck`, `pull`, `push`,
* `range`, `reject`, `remove`, `rest`, `reverse`, `shuffle`, `slice`, `sort`,
* `sortBy`, `splice`, `tap`, `throttle`, `times`, `toArray`, `transform`,
* `union`, `uniq`, `unshift`, `unzip`, `values`, `where`, `without`, `wrap`,
* and `zip`
*
* The non-chainable wrapper functions are:
* `clone`, `cloneDeep`, `contains`, `escape`, `every`, `find`, `findIndex`,
* `findKey`, `findLast`, `findLastIndex`, `findLastKey`, `has`, `identity`,
* `indexOf`, `isArguments`, `isArray`, `isBoolean`, `isDate`, `isElement`,
* `isEmpty`, `isEqual`, `isFinite`, `isFunction`, `isNaN`, `isNull`, `isNumber`,
* `isObject`, `isPlainObject`, `isRegExp`, `isString`, `isUndefined`, `join`,
* `lastIndexOf`, `mixin`, `noConflict`, `parseInt`, `pop`, `random`, `reduce`,
* `reduceRight`, `result`, `shift`, `size`, `some`, `sortedIndex`, `runInContext`,
* `template`, `unescape`, `uniqueId`, and `value`
*
* The wrapper functions `first` and `last` return wrapped values when `n` is
* provided, otherwise they return unwrapped values.
*
* Explicit chaining can be enabled by using the `_.chain` method.
*
* @name _
* @constructor
* @category Chaining

I dislike this. The fact that the items are prepolled annoys me. But there are two problems with trying to "fix"
that. First, fixing it involves changing JVM NetLogo/Headless. To me, that requires a disproportionate amount of
effort to do, relative to how likely--that is, not very likely--that this code is to be heavily worked on in the
future. The second problem is that it's not apparent to me how to you can make this code substantially cleaner
without significantly hurting performance. The very idea of a structure that statefully iterates a collection in
a random order is difficult to put into clear computational terms. When it needs to be done _efficiently_, that
becomes even more of a problem. As far as I can tell, the only efficient way to do it is like how we're doing it
(one variable tracking the current index/offset, and an array where consumed items are thrown into the front).
Whatever. The whole point is that this code isn't really worth worrying myself over, since it's pretty stable.
