# Complexity
## MicroSim spec
- **Recommended sim type:** emergence / agent-based
- **Microsimmability score:** 66/100
- **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below.
### Parameters (tunable controls)
- `Number of parts`
- `Interaction strength`
- `Noise`
### What animates
A system's behavior grows intricate and unpredictable as parts and interaction strength rise.
### Learning objective
Show how interdependence makes system behavior complex.

## Concept summary
Complexity characterizes the behavior of a [[System|system]] or model whose components interact in multiple ways and follow local rules, leading to non-linearity, randomness, collective dynamics, [[Hierarchy|hierarchy]], and [[Emergence|emergence]].
## Build checklist
- [ ] Claim it: set `status: in-progress` + `lease` + `leased_at`
- [ ] Write the child page explaining the concept (tie it back to systems thinking)
- [ ] Finalize parameter ranges and defaults
- [ ] Implement the p5.js sketch (drawing + control regions)
- [ ] Add caption + the learning objective on the page
- [ ] Set `status: done`
## p5.js sketch
```javascript
// MicroSim: Complexity
let controls = {};
function setup() {
// createCanvas(...); create sliders for the parameters above.
}
function draw() {
// background(...); read controls; render emergence / agent-based; respond live.
}
```
