OpenOpt: Ironclad v0.7 released (NumPy on IronPython)
http://openopt.blogspot.com/2008/11/ironclad-v07-released-numpy-on.html
Free Python optimization framework. Thursday, November 27, 2008. Ironclad v0.7 released (NumPy on IronPython). Release v 0.7. I guess it makes possible to use OO and some solvers (like ralg) from IronPython. Subscribe to: Post Comments (Atom). NAS Ukraine cybernetic institute. Cherkasy town, Ukraine. View my complete profile. Ironclad v0.7 released (NumPy on IronPython). CorePy: Assembly Programming in Python. New openopt API func: oosolver. Changes for ralg linear constraints. Any Toronto openopt users?

OpenOpt: OpenOpt (and my) Future
http://openopt.blogspot.com/2008/12/openopt-and-my-future.html
Free Python optimization framework. Monday, December 15, 2008. OpenOpt (and my) Future. My interim in icyb.kiev.ua optimization dept is up to be finished. Today I have spoken with my chiefs from about my further career. They have informed me: because of financial crisis the situation is undefined. Still I have some chances. Moreover, there are some chances I will be permitted to spent some work time for further openopt development. However, it is provided some conditions to be satisfied. Да, тяжелая ситу...

OpenOpt: some changes
http://openopt.blogspot.com/2008/07/some-changes.html
Free Python optimization framework. Thursday, July 3, 2008. Lots of changes, mostly code cleanup (still some more remain to be done) some bugfixes. Objective function in LLSP. Have been changed from Cx-d (lapack-, BVLS. Style) to 0.5* Cx-d 2 ( BCLS. Lsqlin, lots of other LLSP solvers style).These changes are required to simplify writing llsp2nlp converter. Also, some optional fields like those from BCLS will be added to LLSP soon. Subscribe to: Post Comments (Atom). NAS Ukraine cybernetic institute.

OpenOpt: PSwarm 1.3 has been connected
http://openopt.blogspot.com/2008/10/pswarm-13-has-been-connected.html
Free Python optimization framework. Tuesday, October 21, 2008. PSwarm 1.3 has been connected. I have connected new PSwarm version: 1.3. As PSwarm developer Ismael Vaz promised, now Python API has much more available parameters to modify (see updated GLP. Page for details) and outputfcn connected (that improves text and graphics output), so now user-provided callback function(s) can be handled by the solver (also, openopt GUI p.manage() function works better, see previous post.

OpenOpt: new converter: minimax to NLP
http://openopt.blogspot.com/2008/11/new-converter-minimax-to-nlp.html
Free Python optimization framework. Monday, November 17, 2008. New converter: minimax to NLP. I have committed the converter along with usage example. Like MATLAB's fminimax and lots of similar MMP solvers, it works via solving NLP. Let me note that the NLP problem obtained is always constrained (in addition to constraints lb, ub, A, Aeq, c, h from original mmp we get new non-linear inequality constraints written above).

OpenOpt: enhanced iterfcn connection for scipy fmin_cobyla
http://openopt.blogspot.com/2008/11/enhanced-iterfcn-connection-for-scipy.html
Free Python optimization framework. Saturday, November 15, 2008. Enhanced iterfcn connection for scipy fmin cobyla. I have connected changes related to handling of scipy cobyla iterfcn, so now instead of direct line (as before) it looks like this:. Of course, adequate text output is provided as well:. Solver: scipy cobyla problem: unnamed goal: minimum. 0 6115e 01 2.13. 10 2015e 01 -2.82. 20 2029e 01 -6.46. 30 2030e 01 -7.60. 40 2032e 01 -8.70. 50 2032e 01 -10.30. 60 2033e 01 -9.78. 70 2033e 01 -13.41.

OpenOpt: Introducing OpenOpt GUI
http://openopt.blogspot.com/2008/10/introducing-openopt-gui.html
Free Python optimization framework. Wednesday, October 15, 2008. I'm glad to introduce initial version of OpenOpt GUI. I had some months of GUI experience in PyGTK and tcl/tk so I have some experience in GUI development; on the other hand I know very well what's the deuce it is: you have to try all possible combinations of buttons (and the dummy task is NP-Hard of course) to ensure all works ok, to enable/disable buttons in correct order, to story related variables etc. Running OO GUI is performed via.

OpenOpt: OpenOpt release 0.21
http://openopt.blogspot.com/2008/12/openopt-release-021.html
Free Python optimization framework. Monday, December 15, 2008. OpenOpt release 0.21. I'm glad to inform you about new OpenOpt release: v 0.21. Changes since previous release 0.19. June 15, 2008):. Major changes for NLP / NSP solver ralg. New converter: minimax to NLP. PSwarm 1.3 has been connected. Instead of v 1.1. It has much more parameters to modify and ability to use user-supplied callback function. Lots of changes related to oofun: add oovar and oolin, now fixed oovars can be correctly handled.

OpenOpt: Some changes for oofun
http://openopt.blogspot.com/2008/12/some-changes-for-oofun.html
Free Python optimization framework. Monday, December 15, 2008. Some changes for oofun. Some changes for oofun:. Oolin now can handle matrices: oolin(C) creates oofun that returns numpy.dot(C, inp array); oolin(C, d) yields oofun that returns numpy.dot(C, x) d. See updated oolin example.
