I checked out gbrainy 1.62, from a git clone of the project repository. The train question you saw had the correct solution for me, as you can see in the attached screenshot.
It's possible that the version you tested with (1.51) had a bug which has since been fixed, but I haven't checked. ** Attachment added: "Screenshot of the train puzzle, with correct solution acknowledged by gbrainy." https://bugs.launchpad.net/ubuntu/+source/gbrainy/+bug/710442/+attachment/1818991/+files/trains_solved.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/710442 Title: answer to question is wrong -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
