Running `OsilBonminSolver` against JuMP master's `test/nonlinear.jl` results in an undefined reference during the first MINLP test, since Bonmin doesn't give duals (at least not in the results osrl fi…

I can ask whether the objective function is linear, but is there any better way of easily getting the objective coefficients (ideally as a sparse vector, or equivalently the index and value vectors) t…

I wasn't able to find out how to access the counts of the variable types (Tables 3 and 4 in [hooking your solver to AMPL](http://ampl.com/REFS/hooking2.pdf)). Are these currently exposed?

What's the DCP way to represent `y*log(x/y)`? It should be an easy conversion to the exponential cone.

I was looking into preparing an MINLP tutorial and ran into the following error when building CoinOptServices on JuliaBox, using Julia 0.4. Probably related to JuliaBox having a system installation of…

```
This should make solving MINLPs somewhat faster.

- The JuMP column doesn't transmit much information since all solvers are now supported.
- Incorporate Convex.jl into the table. All LP/SOCP solvers are supported so maybe again not too useful to make…

Currently we can add groups of (affine) constraints through the `@addConstraints` macro, e.g.
``` julia
@addConstraints m begin
x >= 1
y - w

Hi and thanks for the help (https://groups.google.com/forum/#!topic/julia-opt/KzkWeVY2woI)
If I use multithreading to optimize more problems in less time I get sometimes an error that `results.osrl` …
