DESCRIPTION:

  APPS is an asynchronous parallel pattern search method for
  optimization. Pattern search uses only function values for
  optimization, so it can be applied to a wide variety of problems. Of
  particular interest to us are engineering optimization design
  problems characterized by a small number of variables and by
  expensive objective function evaluations (typically complex
  simulations that take minutes or hours to run). The name "pattern
  search" derives from the fact that a pattern of search directions is
  used to drive the search. Parallelism is achieved by dividing the
  search directions (and corresponding function evaluations) among the
  different processors. The "asynchronous" part comes about as a
  consequence of the fact that the search along each direction
  continues without waiting for searches along other directions to
  finish, in contrast to the standard parallel pattern search method.
