Average complexity of the Jiang-Wang-Zhang pairwise tree alignment algorithm and of a RNA secondary structure alignment algorithm

International audienceWe prove that the average complexity of the pairwise ordered tree alignment algo- rithm of Jiang, Wang and Zhang is in O(nm), where n and m stand for the sizes of the two trees, respectively. We show that the same result holds for the aver- age complexity of pairwise comparison of RNA secondary structures, using a set of biologically relevant operations
