Details of the hypergraph:
Center node: "string matching with inversions and translocations in linear average time most of the time"
  Abstract: We present an efficient algorithm for finding all approximate occurrences of a given pattern p of length m in a text t of length n allowing for translocations of equal length adjacent factors and inversions of factors. The algorithm is based on an efficient filtering method and has an O(nmmax(@a,@b))-time complexity in the worst case and O(max(@a,@b,@s))-space complexity, where @a and @b are respectively the maximum length of the factors involved in any translocation and inversion, and @s is the alphabet size. Moreover we show that our algorithm has an O(n) average time complexity, whenever @[email protected](logm/loglog^1^-^@em), for @e>0. Experiments show that the proposed algorithm achieves very good results in practical cases.
