Debug binaries are about 4-5 times slower than 'release'
This warning flag indicates that something unusual has happened, but that the problem has been solved OK. I'll add a comment to this effect in the documentation.
OK I'll get to the bottom of this when I investigate #1561
Having looked at your example from #1561, to be more precise `Highs_run(highs)` returning `kHighsStatusWarning` indicates that something unusual has happened, but that the problem _may_ have been solved OK. To...
Beyond looking for logging lines with the prefix "Warning", here is no current way for users to identify retrospectively the reason for the `kHighsStatusWarning` return. The same is true for...
I've reproduced this, and checked that h.setSolution(solution) is returning `OK`, but will have to re-create it in C++ in order to see what's going on.
You're using `h.setSolution(solution) ` correctly and, internally, HiGHS is doing what it can. The reason that it takes as long and performs the same number of simplex iterations is that...
Yes, if you have an LP with an optimal solution, and add constraints that are active at the optimal solution, then the solution for the modified LP will be degenerate,...
If either 'lower' or 'upper' is infinite then 'residual_range' is infinite. I don't know what 1/infinity gives with our infinity (kHighsInf). It might mean residual_rate is 0, so behaviour is...
