I would like to ask that the following features be added for relaxations:
1) Lagrangian relaxations. It would be nice to have a model, plus a specific set of constraints to be dualized. The outpu…

The initial value and gradient is undefined because the start value is `y = 0` and there is `1 / y^2`
This could be classified as expected behavior?
Ipopt is able to solve the model.
## Uno

**Goal:**
Want to add constraints to reduce search space for optimizing the time variables in the chromosome (i.e time of maneuvers). For instance, the next time of maneuver should be greater than t…

The part of the library that solves the Lagrangian dual could be stand-alone and could be made more generic, perhaps for other cut types too.

Thanks for sharing this inspiring work!
I noticed in "get_params_list_with_shape" function, "idx += length" is not added. Without this, it seems like $\mu_i$ and $s$ may not be correctly assigned f…

I did an naive attempt to implement the SQP algorithm, using the package NLOPT. I have pushed the branch "sqp".
To use the branch, please check if NLOPT is installed on your cluster and change the pa…

I am trying to run the beamInCrossFlow tutorial as it is and it fails with floating point exception after the first time step. I am running OpenFOAM 9.0 with solids4foam ver 2.0. The compilation did n…

What is Uno's dual convention? Currently, Uno returns the negative of the Ipopt dual:
See the
```
Dual solution :
c : 1.00000e+00
```
and
```
Dual solution :
c : -1.00000e+00

Here's a model that Ipopt solves but Uno fails on.
Ipopt projects out the fixed variable.
Uno has three variables for some …
