Stuck at edge of primal feasibility for small problem with one 3x3 matrix

7

I have found a small problem for which CSDP has issues with: ``` 4 1 3 0.0 0.0 0.5 1.0 0 1 2 1 0.5 0 1 3 1 0.5...

Implement DiffOpt interface

I was glad to see at Bartolomeo's talk at ICCOPT that OSQP will support querying differentiation information. We developed an extension of MOI for this at https://github.com/jump-dev/DiffOpt.jl. At the moment,...

triu with zero offdiag entries

1

This check: https://github.com/oxfordcontrol/OSQP.jl/blob/f50490536e41da2fef5f03216223090bd30698f8/src/interface.jl#L115-L118 does not work if there is zero offdiagonal entries which makes OSQP fail, see https://github.com/oxfordcontrol/OSQP.jl/pull/90

Fix `Silent`

1

It seems `:verbose` is ignored when it is set by `update_settings!`, i.e. by `osqp_update_verbose`.

Abstract block diagonal matrix

4

We define an abstract block diagonal matrix with an interface similar to the `BlockDiagonal` of this package here: https://github.com/JuliaOpt/SemidefiniteOptInterface.jl/blob/c83bfe9b521eafc5182465cba7c4ce0e9f43ab6b/src/mock.jl#L1-L30 It allows the block diagonal matrices returned by different SDP solvers...

Nondeterministic crash

I am having a very hard time creating a minimal crashing example for this bug because it is nonderterministic. If I execute 2 times the same code it can crash...
