Perfect matching counting problems graph has been proven to be NP-hard. To get the number of perfectly matched general graph is very difficult. The issue has important applications in protein structure prediction
crystal physics
quantum chemistry and computer science. The research on this issue has very important theoretical and practical significance. The counting formula of the perfect matching for graphs 3-nT
4
5-nT
6
and 2-2nQ
2×2
are obtained by applying differentiation
summation and re-recursion . This provides the theory support for the application of perfect matching in graph.
