Did a bit of work and fixed some issues. The inference has some problems and I need to spend more time debugging them. |

where is the code? I can look at it. Specially the way you write constraints is tricky. |

There was a problem hiding this comment.
@bhargav so I fixed the bug you pointer out but didn't help .. :-/
Another thing is I tested by replacing it with a trivial constraints new FirstOrderConstant(true) which should always be feasible; still returning a weird result ...
