Abstract: This paper proposes an efficient algorithm for Fuzzy based Metagraph ADT (Abstract Data Type). It is a hierarchical data structure where every node has one or more data. A mathematical model which encompasses both data type and the functions that operate on the data type is called as an ADT. Fuzzy set ADT integrated with Fuzzy Metagraph can perform different operations such as Union, Intersection, Disjoint Subset Union, Clustering and Searching. The proposed method considerably reduces the time complexity which can be applied to solve a number of problems. Fuzzy metagraph is an emerging technique used in the design of many information processing systems like transaction processing systems, decision support systems, and workflow Systems.
