Changes in version 2020.10-1 (2020-10-19)

    o Added a new derivative free optimizer called MADS: mesh-adaptive direct solver (contributed by Vincent Bechard of Montreal University)

    o In Nelder-Mead, changed the `sgrad' computation back to the original cross-product rather than the (correct) inverse, since this seems to provide better performance

Changes in version 2018.2-1 (2018-4-01)
	o Set oshrink=1 to enable "restarting" of Nelder-Mead due to stagnation (thanks to Simon Wessing)

Changes in version 2017.12-1 (2017-12-20)
	o fixed a bug in the code, which impacts the "restarting" of Nelder-Mead due to stagnation (thanks to Simon Wessing)

Changes in version 2016.7-1 (2011-07-08)

    o Used a slightly modified code for hjk() and hjkb()

Changes in version 2011.8-1 (2011-08-12)

    o Bounds constrained Hooke-Jeeves hjkb()

Changes in version 2011.7-2 (2011-07-26)

    o Bounds constrained Nelder-Mead nmkb().

Changes in version 2011.7-1

    o Hooke-Jeeves minimization routine hjk().

Changes in version 2011.5-1
  
    o Fixed minor bug in the re-definition of objective function inside
      for maximization.

Initial version
