Windows users: workaround for incompatibility with MinGW

Dear Windows users,

The latest version of MinGW has made some changes in the pthread library, breaking the compatibility with Bocop. Until this issue is fixed, we provide an archive of a compatible MinGW installation on the Download page. All you have to do is to extract the archive to a location without spaces in its name (for instance C:, but NOT C:Program Files).

We are sorry for the inconvenience, and are working on a solution to this issue.

The Bocop team

Bocop 1.1.2 release

Bocop 1.1.2 is out.

Bocop 1.1.0 release

Bocop 1.1.0 is out.

Main changes include:

  • new Qt GUI available for linux precompiled packages (Mac and Windows versions are still under testing)
  • multipliers for the constraints, as well as the adjoint states, are now saved in .sol files and available for visualization. Reoptimization is now possible as a warm start, reusing the multipliers from the previous solution for initialization in addition to the primal variables. Reoptimization using only the primal variables is now labeled as cold start.
