- Law of Least Effort says that the pathway that takes the least amount of effort is used for accomplishing any task.
In biology
- Evolution has shaped species to optimise for the amount of information processing. This is precisely why we have such strong patterns all across.
- For example- guess how we humans can recognise people from silhouette?
In computing
- Computing algorithms are designed to optimise for utilising as little computational power as possible.
- This is why just the functionality of any feature is not enough; the implementation (can be crudely said to be algorithm) also matters.
- An optimal algorithm might reduce the time of an operation by orders of magnitudes—e.g., from 50 minutes to 500 milliseconds.
