<p>Hi all,<p>
<br /> I'm glad to inform you about new OpenOpt Suite release 0.39 (2012-June-15):<br /> <a href="http://openopt.org/interalg">interalg</a>: add categorical variables and general logical constraints, many other improvements<br /> Some improvements for automatic differentiation<br /> <a href="http://openopt.org/DerApproximator" target="_blank">DerApproximator</a> and some OpenOpt / FuncDesigner functionality now works with <a href="http://openopt.org/PyPy">PyPy</a><br /> New solver lsmr for dense / sparse <a href="http://openopt.org/LLSP">LLSP</a><br /> oovar constructors now can handle parameters lb and ub, e.g. a = oovar('a', lb=-1, ub=[1,2,3]) (this oovar should have size 3) or x = oovars(10, lb=-1, ub=1)<br /> New FuncDesigner function hstack, similar syntax to numpy.hstack, e.g. f = hstack((a,b,c,d))<br /> Some bugfixes<p>
<br />
<p>I have some progress toward solving in <a href="http://openopt.org/FuncDesigner">FuncDesigner</a> linear DAE (differential algebraic equations, <a href="http://openopt.org/DAE">example</a>) and Stochastic Opimization (<a href="http://pastebin.com/e01XWNdD">example</a>), but this is too premature yet to be released, there is 60-70% probability it will be properly implemented in next OpenOpt release.<p>
<br />
<p>In our <a href="http://openopt.org">website</a> you could vote for most required OpenOpt Suite development direction(s).<p>
