Software for the Closest Substring Problem and the Planted (L,d)-Motif Problem
   This site provides a program for solving the closest substring problem and the planted (L,d)-motif problem.

The program:   After downloading the program, you can run it as follows:
         Provable   fileName   L   d
where fileName is a file containing sequences in Fasta format, L is the length of the center substring (or the planted motif) to be found, and d is an upper bound on the minimum distance between the center substring (or the planted motif) and a substring of each sequence in the file.

A program for generating random instances of the planted (L,d)-motif problem:   After downloading this program, you can run it as follows:
         randGen   n   K   s   L   d   fileName
where n is the number of sequences to be generated, K is the length of each sequence to be generated, s is the size of the alphabet of the sequences to be generated, L is the length of the motif to be planted, and d is the number of positions of the motif to be modified when it is planted in each sequence, fileName is a file to hold the generated sequences in Fasta format.

An example for which PMSPrune does not work.
