1, Occam's razor principle is also called Aokang razor. This principle was put forward by14th century logician ockham. Occam's razor principle only recognizes what really exists, and thinks that those empty and common things are useless and should be shaved off. Ockham advocates the principle of thinking economy, that is, to sum up, if it is unnecessary, don't add entities.

2. Occam's razor principle is simply to simplify things, grasp the root causes, solve the essence, and don't make things complicated, so as to deal with things effectively.

3.Solomonoff's inductive reasoning theory is the mathematical expression of Occam's razor: among all the computable theories that can perfectly describe the existing observations, the shorter computable theory has greater weight in estimating the probability of the next observation.

4. Occam's razor principle can be traced back to early philosophers, such as Dunn Scholes (1265_ 1308), Robert Gloucester (1 175- 1253) and Maimonide (Moses).

5. Occam's razor law advocates simplification. Occam's razor law holds that keeping things simple is the most effective way to deal with complicated things. Later, this principle was widely used in management.
