inaccurate derivatives of matrix logarithm

1

The gradient of of the matrix valued function `F(X) = log(X)` or the Hessian of the scalar valued function `f(X) = tr(X * log(X))` has an analytic form e.g. Equation...

Julia crashing (possibly due to project Pardiso version)

7

I am seeing crashing/segfaults from Pardiso.jl with (project) Pardiso. I'm not sure if this is related, but the version of Pardiso that I got with my academic license was labelled...

nameclash on Windows for .pdb files

7

When building with MSVC the .pdb file for the .dll (which is needed for the debugger) is overwritten by the .pbd file for the executable. This happens because both are...

Decrease delta when the algorithm starts to diverge. @jeanpauphilet I'm not sure what you would like to do with the progress bar? If we start from scratch every time we...

saved MIP solutions pool is empty when solution is found during presolve

2

I noticed that when an optimal solution is found during presolve, it's not recorded or returned with getSavedMipSolutions(). Any reason not to record it e.g. [here](https://github.com/ERGO-Code/HiGHS/blob/master/src/mip/HighsMipSolver.cpp#L127)?

Wrap a routine for nonsymmetric LHSs

update termination message for `NearOptimal` status

1

`optimal solution found; terminating` can be confusing

When using the 1s vector as the initial point, we restrict the Ps that parameterize the cone (e.g. in our scheme, interpolation points have to come from the domain of...
