# Algorithmic efficiency
## MicroSim spec
- **Recommended sim type:** complexity / growth
- **Microsimmability score:** 86/100
- **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below.
### Parameters (tunable controls)
- `Input size n`
- `Complexity class`
- `Constant factor`
### What animates
Cost curves for O(1), O(n), O(n log n), O(n^2) race as input size grows; the chosen class and constant reshape the winner.
### Learning objective
Relate runtime growth to asymptotic complexity and input size.

> In computer science, algorithmic efficiency is a property of an algorithm which relates to the amount of computational resources used by the algorithm. Algorithmic efficiency can be thought of as analogous to engineering productivity for a repeating or continuous process. ([Wikipedia](https://en.wikipedia.org/wiki/Algorithmic_efficiency))

## Concept summary
Algorithmic efficiency measures the time and space an [[Algorithm|algorithm]] consumes as a function of input size (Big-O [[Complexity|complexity]]).
## Build checklist
- [ ] Claim it: set `status: in-progress` + `lease` + `leased_at`
- [ ] Write the child page explaining the concept (tie it back to system quality attributes)
- [ ] 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: Algorithmic efficiency
let controls = {};
function setup() {
// createCanvas(...); create sliders for the parameters above.
}
function draw() {
// background(...); read controls; render complexity / growth; respond live.
}
```
