Abstract: AMSM is a new adapted multiple strings matching algorithm，which can search the mass data by one-pass with space-efficient and time-efficient.It can be used for the real-time network information monitoring and DNA sequences matching.A summary about the state of art of exact pattern matching algorithms is introduced in this paper，AMSM is combined of SBOM and WuManber algorithms and it employs two approaches： precise bad block character shift and weakened Oracle shift to improve the original algorithm.From a practical standpoint，the AMSM runs faster than state-of-art algorithm such as WuManber and SBOM in many cases.From a theory point，it is a simulator of WuManber or SBOM algorithm using each argument profile.
