定义

Among competing hypotheses, the one with the fewest assumptions should be selected.

We should avoid looking for excessively complex solutions to a problem and focus on what works, given the circumstances. Occam’s razor is used in a wide range of situations, as a means of making rapid decisions and establishing truths without empirical evidence.

Occam’s razor is frequently used by scientists, in particular for theoretical matters. The simpler a hypothesis is, the more easily it can be proved or falsified.

“Everything should be made as simple as possible, but not simpler.”
