Hi all,
I'm glad to inform you about new OpenOpt Suite release 0.42
(2012-Sept-15). Main changes:
* Some improvements for solver interalg, including handling of
categorical variables
* Some parameters for solver gsubg
* Speedup objective function for de and pswarm on FuncDesigner models
* New global (GLP) solver: asa (adaptive simulated annealing)
* Some new classes for network problems: TSP (traveling salesman
problem), STAB (maximum graph stable set)], MCP (maximum clique problem)
* Improvements for FD XOR (and now it can handle many inputs)
* Solver de has parameter "seed", also, now it works with PyPy
* Function sign now is available in FuncDesigner
* FuncDesigner interval analysis (and thus solver interalg) now can
handle non-monotone splines of 1st order
* FuncDesigner now can handle parameter fixedVars as Python dict
* Now scipy InterpolatedUnivariateSpline is used in FuncDesigner
interpolator() instead of UnivariateSpline. This creates backward
incompatibility - you cannot pass smoothing parameter (s) to interpolator
no longer.
* SpaceFuncs: add Point weight, Disk, Ball and method contains(), bugfix
for importing Sphere, some new examples
* Some improvements (essential speedup, new parameter interpolate for
P()) for our (currently commercial) FuncDesigner Stochastic Programming
addon
* Some bugfixes
In our website ( http://openopt.org ) you could vote for most required
OpenOpt Suite development direction(s) (poll has been renewed, previous
results are here).
Regards, D.
