Reeb　graph　is　a　graph　which　can　represents　the　skeletal　and　topological　structure　of　a　3D　shape,　and　Multiresolutional　Reeb　Graph　as　an　improvement　Of　Reeb　graph　which　include　a　series　of　Reeb　graphs　for　an　object　at　various　levels　of　detail,　is　more　efficient　than　original　Reeb　graph　and　so　widely　used　in　topology　based　searching　fields.　This　paper　proposes　a　improved　algorithm　for　matching　MRGs.
