Hello, I encountered problems with the ralg solver in OpenOpt. the example nlp_3.py, supplied with the OpenOpt library crashed on two computers. On an ubuntu linux machine, the program simply stopped without further information. On a windows machine, with entought suite, there was a windows error message "pythonw caused a fatal error and it will be closed". The problem disappeared when I erased ralg from the solvers list. It did not occur with lincher and scipy_cobyla solvers. On both machines, the openopt installation was from the latest tarball (no more than week old). What is the problem ? Can it be corrected ? Another small request concerning OpenOpt. Is it possible to provide an example for use of scipy_tnc and scipy_lbfgsb from openopt ? Can these solvers work with linear equality constraints ? Thanks Eli
