One more followup, explaining the example a little bit --
In the example we have 5 symbolic variables, $w_1,w_2,w_3,\alpha,\beta$, and six numbers $X_1,X_2,X_3,Y_1,Y_2,Y_3$, and we are trying to maximize $\sum w_i$ subject to $w_i^2 = w_i$ (i.e. $w_i$'s are boolean) and $\sum w_i X_i (X_i \beta + \alpha - Y_i) = 0$.
Note that this optimization problem has a nearly-feasible solution with $w_1 = w_2 = w_3 = 1$, $\alpha = -96.6442179237748$, and $\beta = 160.8249567162244$. Which means that what SCS is saying can't be right; the best upper bound here has to be $3$ (via the constraints $w_i^2 = w_i$ you should get the upper bound of $3$).
For fun, I ran with CSDP as well; it agrees (more or less) with SCS. Here's the output:

So, CSDP doesn't solve all the way, but it says that opt should be between 2.01 and 2.25, which is consistent with SCS but inconsistent with Mosek.
It seems Mosek doesn't converge, the solution_summary
gives
* Solver : Mosek

Maybe I'm misreading the output of solution summary
, but it looks like Mosek has bounded the optimum value between 2.96375 and 2.96955, no? (That is pretty confusing because we're solving a minimization problem, so the dual bound should be less than the best primal feasible solution...)
Maybe I'm misreading the output of solution summary
The bits to read are:
Termination status : SLOW_PROGRESS Primal status : UNKNOWN_RESULT_STATUS Dual status : UNKNOWN_RESULT_STATUS
Mosek failed. It didn't find an optimal solution, and it isn't sure what the current solution values represent. Typically, we'd expect
Termination status : OPTIMAL Primal status : FEASIBLE_POINT Dual status : FEASIBLE_POINT
a) thanks for the quick attention -- I really appreciate it!! b) that's very strange to me -- it's not such a crazy SDP. Is there some rule of thumb advice for what to do when Mosek doesn't converge? c) the issue with SCS and CSDP still seems unresolved -- it seems like they are giving optimal values which should be infeasible (their optimal values are around 2, and it shouldn't be possible to do better than 3)
c) the issue with SCS and CSDP still seems unresolved
In most cases, I would say trust Mosek over SCS and CSDP. If Mosek can't solve it and SCS and CSDP are reporting solutions, then it's likely that the solutions they report are incorrect, and that Mosek is "correct" in it being a difficult SDP to solve.
Hi @samhopkins. Not sure if this helps, but regarding the output from the second-order solvers: we can't use the objective values early on to conclude that the optimal objective value is in some interval. It's normal for the primal/dual objectives to oscillate throughout the solve.
Closing because this is not a bug in SumOfSquares.jl. Mosek doesn't converge for this problem.
I am working on a problem involving optimizing a polynomial over an ideal. I've put together an SoS-style SDP for this, using SumOfSquares.jl. I'll give a full example replicating this behavior below, but the flavor of the thing is:
The weird thing is: I get different optimal values if i use
SoSModel(SCS.Optimizer)
versusSoSModel(Mosek.Optimizer)
. Unless I am misreading the outputs of Mosek and SCS, the difference in optimal values is well outside the error tolerance/duality gaps. I would love some help diagnosing this issue -- is this a bug in SoSTools? JuMP? My code?Here's the smallest counterexample I have so far:
On my machine, using SCS I get objective value
2.039893
, while using Mosek I get objective value2.9999121506536075
(i.e., 3, up to numerical error).Please let me know if there's anything else I can provide. In the meantime I'll start looking for a smaller counterexample.
