Week Summary 8

This week I learned the decision tree and the decision table. A decision table is a tool used to express the processing logic. A decision table is usually made up of four parts, the left upper list is all the conditions, the lower left is for all possible operations, the upper right part represents a matrix of various combinations of conditions, and the lower right part corresponds to the action that should be applied to each condition combination.

The decision tree, also known as Policy tree, was first used in the article "The Abstract Information channel model and its application" in the 1th "Computer research in Development" in 1992 by the domestic scholar bells and so on, which is suitable for describing problem processing with multiple judgments, and each decision is related to some conditions. When using decision tree to describe, we should distinguish from the textual description of the question which are the judging conditions, which are the decision-making, according to the conjunctions in the descriptive material to find the subordinate relation, the side relation, the choice relation, and construct the decision tree according to them.
