Hi all, I encountered a problem related to the python interface of algencan. See http://www.ime.usp.br/~egbirgin/tango/py.php The backtrace of my small test (comparison.py) is as follows: starting solver ALGENCAN (license: GPL) with problem unnamed *** glibc detected *** double free or corruption (out): 0x0000000000e17a40 *** PYTHON INTERFACE ERROR: in inip, PyEval_CallFunction returned NULL Program received signal SIGABRT, Aborted.

Nils, try using p.xlabel = 'nf' this is temporary name for "number of function evaluations", I will think what is better name for the case, and then commit it into OO doc. This is more appropriate vs your "iteration" that you have chosen for your x label. Your "iteration" is just a single objfunc evaluation, while users will suppose solvers have different iterations with different number of objFunc evaluations in each one. Also, take into account, that ralg can yield infeasible iteration points, so your single-subplot picture doesn't provide all convergence info. Ralg is intended to handle lb-ub problems more bette in future. Regards, D. Nils Wagner wrote:

Hi Dmitrey, Thank you for your comments. BTW, do you have an optional specification file algencan.dat that you can send me ?

I just noticed the message
The optional specification file algencan.dat was not found in the current directory (this is not a problem nor an error). The default values for the ALGENCAN parameters will be used.

This output is generated by ALGENCAN, not OO. You'd better contact ALGENCAN developers about the file. Regards, D.
