[SciPy-dev] SLSQP Constrained Optimizer Status
Tue Dec 18 14:44:12 CST 2007
Hi Rob, could you check the line 224 (slsqp.py)
a = numpy.concatenate( (fprime_cons(x),zeros([la,1])),1)
I found the problem is here (lines 163-165):
meq = len(eqcons) # meq = The number of equality constraints
m = meq + len(ieqcons) # m = The total number of constraints
la = array([1,m]).max() # la =
So when user pass for example f_eqcons instead of eqcons, there is no
appropriate handling of the situation in the code above these lines, so
it produces la = 1 and error in concatenate.
I will try to continue connecting slsqp to OpenOpt after you'll inform
about fixing the bug, ok?
