I have opened it since people might want to use it and it would be easier for you to control it. But why does infinity is causing a problem? I thought |
|
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 unchanged, but I don't want it unguarded. I will look at this, don't worry! |

Under Windows, 1.0 / Highs_getInfinity(highs) returns 0.0 |

That's good to know, thanks |

Scaled the residual for numerical tolerance.
