OpenOpt 0.18

Hi all,
I'm glad to inform you about new OpenOpt release: v 0.18.

Changes since previous release 0.17 (March 15, 2008):
  • connection to glpk MILP solver (requires cvxopt v >= 1.0)

  • connection to NLP solver IPOPT (requires pyipopt installation, that is currently available for Linux only)

  • major changes for NLP/NSP solver ralg

  • splitting non-linear constraints can benefit for some solvers

  • unified text output for NLP solvers

  • handling of maximization problems (via p.goal = 'max' or 'maximum')

  • some bugfixes, lots of code cleanup

Regards, Dmitrey.
