Oh, I should have closed that. I opened that to work around the fact that processing the tree was recursive and failed on deep trees. Now that we have flat trees, it isn't needed so much. Plus, I think simplify actively breaks the balanced tree: The real problem is that there is no way to represent a sum of more than two elements internally. |

yes, that's true. Maybe #67 is still relevant after all. That could be resolved by a different representation disscussed here: #37 (comment). But as you said, it is more ambitious. |

Yes #67 is still totally relevant. For medium or large problems, rust-lp-modeler takes much longer to create the problem than it takes to actually solve it ! I am working on #37 (comment) , but as a separate crate, as I want to be able to make the right design decisions without worrying about backwards compatibility. I'll let you know when I have something to show. |
