**Motivation**
As well as satisfaction problems (find me the x that satisfies these constraints), Minion and other solvers support optimisation problems (find me the x that fulfills the most/least …

I found your solution very helpful for this problem.. Very elegant solution. But I wonder , is there any more optimisation we can do on this? The same problem constraint increased to matrix of size 10…

Hi,
Is it possible to use `pySOT` with expensive blackbox constraints?
For example, if the `objfunction()` method in the optimisation problem class can be written to use an external piece of sim…

The metrics system is not fully thread-safe at the moment, due to some issues:
1. `IncMetrics` inner state is mutated on serialisation. This causes race conditions when the `write()` function is ca…
