## Optimization Design Principles
* **Definition**: The mathematical process of finding the best solution within given limitations.
* **Design Variables**: Parameters that can be adjusted (e.g., length, thickness).
* **Objective Function**: The primary goal to maximize (efficiency, strength) or minimize (cost, weight).
* **Constraints**: Real-world boundaries like budget (<$10,000) or physical properties (thickness > 2mm).

## Example: The Soda Can Problem
* **Goal**: Maximize volume (V) using independent variables: Radius (r) and Height (h).
* **Constraint**: Fixed surface area of 300 cm² (limited aluminum).
* **Optimal Solution**: Found at the peak of the Volume vs. Radius curve where volume is approximately 290.3 cm³ at a radius of 3.9 cm.

## Summary
* Design is a trade-off where success is defined by the objective function and the 'playground' is defined by the constraints.
