                  The Fortran95 code VTDIRECT95, based on the original MPI,
                  has been modified to use MPI-2. An option for VTDIRECT95
                  is to divide the feasible box into subdomains, and
                  concurrently apply the global direct search algorithm
                  DIRECT within each subdomain. When the number of
                  subdomains is greater than one, a bug causes VTDIRECT95
                  to occasionally sample outside the given feasible box,
                  which is serious if the objective function is not defined
                  outside the given box. This bug has been fixed, and the
                  sample output files have been updated to reflect the
                  correction. For completeness, the package VTDIRECT95 now
                  contains both the MPI-1 (with the multiple subdomain bug
                  fixed) and the MPI-2 versions of the code. ",
