HOPSPACK Release History

  • 2.0.1 - March 26, 2010 (SVN rev 167)
    • New Feature. The release adds a new capability to project a trial point to the nearest point satisfying all variable bounds and linear constraints. In particular, the start point does not have to be feasible.
    • New Feature. The GSS-MS solver is modified to accept problems with linear constraints. Start points are generated randomly within the variable bound constraints, then projected to the nearest point that satisfies linear constraints. If the user supplies an initial point, GSS-MS tries it as the first start point.
    • Bug Fix. Trial points produced by the GSS solver are adjusted to honor variable bounds if roundoff error cause a violation. The bug is seen on problems with linear constraints. The adjustment will not exceed the value of parameter Active Tolerance.
    • Bug Fix. Certain C++ #include headers required by the gcc 4.4.1 compiler are added.
    • Bug Fix. In the User Manual and examples, the proper return status when evaluating a function by System Call is clarified. The old description was unclear, and some examples did not consistently return the correct status.
  • 2.0.0 - Nov 2, 2009 (SVN rev 144)
