I think it is a good time for us to start discussing the solver interface. My general impression is that trying to fit the solver we are implementing into the ``minimize`` interface may not be practic…

Ok, so I did some research today and decided to take a bottom-up approach in implementing the algorithm. I intend to follow the sequence:
- [x] 1. Implement the projected CG;
- [x] 2. Implement th…

A number of problems involve minimizing a function on a Riemannian manifold defined by geometric constraints. An example is the eigenvalue problem by the minimization of the Rayleigh quotient under or…

### Results of the SQP solver on the test problem ``ELEC``.
This problem is described in \[1\], problem 2, and consist of given ``np`` electrons, find the equilibrium state distribution (of minima…

I played around with the gbac instance reduced_UD10-gbac (from the MiniZinc benchmark library) and I think I observed a bug in flattening.
gbac is a course scheduling problem; there are curricula a…

Specifically, when I compare
```
gfortran -O3 perf.f90 && ./a.out
gfortran -O3 -march=native -ffast-math -funroll-loops perf.f90 && ./a.out
```
on my machine, then I get 2x speedup on the `iterat…

Since we've added and are adding a number of new solvers, we probably need to develop a consistent naming approach. For example, we currently have sopt_l1_solver (Douglas-Rachford), sopt_l1_sdmm (SDM…

From what I know, TensorFlow doesn't handle constrained optimisation easily. Therefore, I would want an unconstrained support vector machine (SVM) cost function.
Indeed, I could minimise some unconst…

Hi,
I am applying and disabling constraints following user interaction by calling 'force.constraints([]).start()'
with and without elements in the constraints array.
Problem is, the layout is chan…
