Finding a Smooth Frame Decomposition of a Graph

Let G be a graph and A be a subset of the edges of G. A frame decomposition of G is a pair (G-A,A) such t ha t G-A is connected. A smooth frame decomposition of G is a frame decompo sition satisfying the two conditions: (1) Every leaf of G-A has a connected cotree and (2) The set of bridges of G-B(G-A) is A, where B(G-A) is the set of bridges of G-A. An efficient algorithm on finding a smooth frame decompositi on of a graph is provided.
