ANN: OpenOpt 0.19 (free optimization framework, Python language)
Hello,
We're pleased to announce:
OpenOpt v 0.19, free (license: BSD) optimization framework
(written in Python language) with connections to lots of solvers (some
are C- or Fortran-written) is released.
Changes since previous release 0.18 (June 15, 2008):
* Some changes for NLP/NSP solver ralg (especially related to
handling linear constraints Ax = b, Aeq x = beq, lb = x = ub)
* Bugfix for ralg and IPOPT linear constraints handling
* ALGENCAN v 2.0.x has been connected (v 1.0 is no longer
supported, v 2.0.3 or later is required)
* Bugfix for constrained NLSP graphic output (constrained nssolve
isn't turned to latest ralg version yet)
* Scale parameter for lpSolve (p.scale = {False} | True | 0 | 1)
* New OO class LLAVP (linear least absolute values aka linear
least deviations)
* Improved handling of non-linear functions with restricted dom
* GLP (global) solver galileo now can handle integer problems (via
p.useInteger = 1 or True)
* Another one GLP (global) solver connected: pswarm
* Lots of work related to oofun concept (see OO Doc page for
details)
* Add converters llsp2nlp, llavp2nsp
* Convenient handling of maximization problems (via p.goal = 'max'
or 'maximum')
* Some code clean up and bugfixes
Backward incompatibility:
* Changed objective function in LLSP
* MATLAB-style gradtol renamed to gtol (for to provide same syntax
to scipy.optimize fmin_bfgs, fmin_cg and less-to-type)

ETS 3.0.2 released!
I'm pleased to announce that the Enthought Tool Suite (ETS) 3.0.2 has just been tagged and released! Source distributions (.tar.gz) have been pushed to PyPi. Window's binaries will be built and uploaded to PyPi over the next 24 hours or so. You can update to ETS 3.0.2 like so: easy_install -U ets=3.0.2 Changes --- ETS 3.0.2 is an update to ETS 3.0.1 that includes the following changes: * Update of Enable to fix problems doing 'setup.py install'. * Update of ETSProjectTools to fix bugs and improve the help messages. * Update of Mayavi to fix bugs found during the SciPy conference. * Update of Traits, TraitsGUI, and TraitsBackend* to fix a number of issues (see https://svn.enthought.com/enthought/query?milestone=Traits+3.0.2) What is ETS? -- The Enthought Tool Suite (ETS) is a collection of components developed by Enthought and our partners, which we use every day to construct custom scientific applications. It includes a wide variety of components, including: * an extensible application framework * application building blocks * 2-D and 3-D graphics libraries * scientific and math libraries * developer tools The cornerstone on which these tools rest is the Traits package, which provides explicit type declarations in Python; its features include initialization, validation, delegation, notification, and visualization of typed attributes. More information is available for all these packages from the Enthought Tool Suite development home page: http://code.enthought.com/projects/tool-suite.php -- Dave -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html
GOZERBOT 0.8.2-BETA released
It is time for a new gozerbot release so we are pushing a new BETA for the world to test. This time the change is rather big as most plugins are removed from the core and put into there own tarball. So if you want to try out 0.8.2-BETA for us and report any problems with it on http://dev.gozerbot.org/ or in our channel #dunkbots on IRCnet we would very much appreciate it. You can also contact me at [EMAIL PROTECTED] Download can be done from our website http://gozerbot.org/ new features: * most plugins removed from core .. this keeps the base of the bot as small as possible * missing plugins can be installed via internet or via tarball * rewritten core .. callbacks and commands when not threaded are not executed in the main loop anymore but instead in what are called “runners”, threads that do the jobs. this limits the threads that are launched * new debug mode that enables more verbose logging (stacktrace) * a REST server and client have been added to the core .. the cloud plugin uses these to communicate between bots. data is transfered in json format * new plugins are added to the plugin collection o powernick (core) .. a plugin to relay the log file to an OPER via DCC CHAT o throttle (core) .. throttle users to max number of commands per minute o cloud (myplugs) .. connect gozerbots together o traclog (myplugs) .. log channel in a format suitable for integration with trac o register (myplugs) .. enables users to register themselves with the bot o anon (myplugs) .. register users on channel join * config changes are now written to the config file instead of a pickle TAKE NOTE: most of the plugins are removed from the core bot .. you can use the !install-defaultplugs command to get most of these plugins .. otherwise see !install-list of plugins that can be installed About gozerbot: Requirements * a shell * python 2.4 or higher * if you want to remotely install plugins: the gnupg module * if you want mysql support: the py-MySQLdb module * if you want jabber support: the xmpppy module Why gozerbot? * provide both IRC and Jabber support * user management by userhost .. bot will not respond if it doesn't know you (see /docs/USER/) * fleet .. use more than one bot in a program (list of bots) (see / docs/plugins/FLEET/) * use the bot through dcc chat * fetch rss feeds (see /docs/plugins/RSS/) * remember items * relaying between bots (see /docs/plugins/RELAY/) * program your own plugins (see /docs/PROGRAMPLUGIN/) * run the builtin webserver (see /docs/plugins/WEBSERVER/) * query other bots webserver via irc (see /docs/plugins/ COLLECTIVE/) * serve as a udp - irc or jabber notification bot (see /docs/ plugins/UDP) * mysql and sqlite support the gozerbot development team -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html
