## Given a permutation T of 1 to n, and a permutation P of 1 to k, for k < n, we wish to find a k-element subsequence of T whose elements are ordered according to the permutation P. For example, if P is ( 1,2, . . . , k), then we wish to find an increasing subsequence of length k in T; this specia
GivenapermutationPof{l,..., k}andTof{l,..., n}, k < n, the pattern matching problem for permutations is to determine whether there is a length k subsequence of T whose elements are ordered in the same way as the elements of P. We present an 0( kn4) time and 0( kn3) space algorithm for finding a matc
