چکیده
We study the complexity of the Subgraph Bisimulation Problem, which stands to Graph Bisimulation as Subgraph Isomorphism stands to Graph Isomorphism and we prove its NP-Completeness. Our analysis is motivated by its applications to Semistructured Databases.

The Subgraph Bisimulation Problem and its Complexity
In this paper we study the complexity of the Subgraph Bisimulation Problem, which stands to graph bisimulation as subgraph isomorphism stands to graph isomorphism, and we prove its NP-completeness. Our analysis is motivated by recent requirements coming from semistructured databases, where Subgraph Bisimulation can be used for retrieving semistructured data, even in presence of ‘cyclic’ queries...
متن کاملBisimulation for BL-general fuzzy automata
In this note, we define bisimulation for BL-general fuzzy automata and show that if there is a bisimulation between two BL-general fuzzy automata, then they have the same behavior.For a given BL-general fuzzy automata, we obtain the greatest bisimulation for the BL-general fuzzy automata. Thereafter, if we use the greatest bisimulation, then we obtain a quotient BL-general fuzzy automata and th...
متن کاملUpdates for Structure Indexes
The problem of indexing path queries in semistructured/XML databases has received considerable attention recently, and several proposals have advocated the use of structure indexes as supporting data structures for this problem. In this paper, we investigate efficient update algorithms for structure indexes. We study two kinds of updates — the addition of a subgraph, intended to represent the a...
متن کاملI-homomorphism for BL-I-General L-fuzzy Automata
Taking into account the notion of BL-general fuzzy automaton, in the present study we define the notation of BL-intuitionistic general L-fuzzy automaton and I-bisimulation for BL-intuitionistic general L-fuzzy automaton.Then for a given BL-intuitionistic general L-fuzzy automaton, we obtain the greatest I-bisimulation. According to this notion, we give the structure of quotient BL-intuiti...
متن کاملOptimal Coding Subgraph Selection under Survivability Constraint
Nowadays communication networks have become an essential and inevitable part of human life. Hence, there is an ever-increasing need for expanding bandwidth, decreasing delay and data transfer costs. These needs necessitate the efficient use of network facilities. Network coding is a new paradigm that allows the intermediate nodes in a network to create new packets by combining the packets recei...
