Assertion in ClpNonLinearCost::checkInfeasibilities: `lowerValue <= upperValue' failed

Open christoph-cullmann opened this issue 4 years ago • 1 comments

e.g. run a debug build of cbc with

cbc value_231271646004486.lp -cuts=off -solve

this will result in:

cbc: src/Clp/src/ClpNonLinearCost.cpp:1064: void ClpNonLinearCost::checkInfeasibilities(double): Assertion lowerValue <= upperValue' failed.`

-cuts=off is needed (or some other subset of cuts)

Other ILP to reproduce this, needs no special options for cbc
