Distribution network topology analysis and application based on object oriented and linked storage structure;

This paper proposed the method of designing linked storage structure of the binary tree in DNA computer,which utilized the biological characteristics of DNA molecules and ligases.

There are two storage structures of dada in computer and linked storage structure is one of them.

This paper presented the directed itemsets graph to store the information of frequent itemsets of transaction databases,and put forward the trifurcate linked list storage structure of directed itemsets graph,and provided the mining algorithm of maximal frequent itemsets based on directed itemsets graph.

This paper presents the directed itemsets graph to store the information of frequent itemsets of transaction databases,and puts forward the trifurcate linked list storage structure of directed itemsets graph,and provides the mining algorithm of frequent closed itemsets based on directed itemsets graph.

According to the insufficiency in data storage of the multi-rigid-body system,the research on relation between the structure of multi-rigid-body system and the directed graph in graph theory is done,and a new linked storage model based on orthogonal list is proposed.

This thesis started from basic idea if inserting element and deleting element from linked storage of linear list,differently giving the algorithm idea for implementation of the operation.
