Strategy
It has been said that there is more than one way to skin a cat. I have, wisely, never looked into how many ways there are. The same is frequently true for algorithms in computer programming. Frequently, there are numerous versions of an algorithm that trade off memory usage for CPU usage. Sometimes, there are different approaches that provide different levels of fidelity. For example, performing a geolocation on a smart phone typically uses one of three different sources of data:
- GPS chips
- Cell phone triangulation
- Nearby WiFi points
Using the GPS chip provides the highest level of fidelity; however, it is also the slowest and requires the most battery. Looking at the nearby WiFi points requires very little energy and is very quick; however, ...
