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.
