Presolve isn't identifying redundant constraints in QCPs

    Hi Omkar,

    Thanks for raising this. I believe it's not too unusual for some redundant constraints to make it through presolve, as checking redundancy for all subsets of constraints can be expensive but have limited benefits for the solver. However it is not expected that the optimal solution values would differ.

    Could you please share the original models? As you point out the presolved results you have posted here are very different models (actually when I run these, the first appears to be non-convex infeasible, and the second convex and feasible) so it would help to see the original source.

    Hi Simon,

    Thanks for your response. Below, I copy-pasted the contents to the mps files for the smaller and larger models -- let me know if there is a better way to share the original models. In case it helps, I used a diff tool to verify that the only differences between the two models are related to R140, i.e., the redundant constraint (see picture below).

    Hello Simon,

    In case it helps, I also uploaded the mps files in my previous post to a Dropbox. Rather than copy-pasting these files from above, you can download them using the links below:

    If you'd like to see the lp and log files from my original post, please use this link: https://www.dropbox.com/sh/6cnr9j7fdchid0a/AAAwzZQjw3NJ86fGNyWCQ3KUa?dl=0

    Thanks for looking into this. Hope to hear from you soon.
