When investigating a problem with my tool (to figure out why Couenne was marking it as unfeasible when it was supposed to have a solution), I encountered a peculiar situation:
[Cf the attached .mod file]
(i) When using the first cost function (which is commented, line 14), Couenne marks the problem as unfeasible
(ii) When using the second cost function, obtained by simplifying the "TX_2" on both sides of one of the fractions, the problem becomes feasible.
(for reference, the problem is indeed feasible)
Therefore, would it be possible to add a preprocessing step or a fix to manage this issue?
Hello,

Thank you for your support, Guillaume I.
