In principle it is the conditional probability, joint probability method to simplify and streamline the process in this note the number of database scans and efficiency improvements, which make the algorithm more practical.

It is a principle of conditions on the methods of probability, the joint probability, and as a result of this simplification process simplification in the attention of database scanning frequency and improve efficiency, thereby allowing more practical algorithms.

In its principle is to the conditional probability, the joint probability method simplification, and has paid attention in this simplification process to the database scanning number of times and the efficiency improvement, thus causes the algorithm practical.

Principles on which it is the method of conditional probabilities, the joint probability, and note that in this simplified procedure is made to the database scanning times and improved efficiency, so as to make the algorithm more practical.
