Message
Invalid bound for a decision variable: {...}
Cause
A decision variable’s bound was rejected when constructing the OMMX bound — the evaluated lower bound is greater than the upper bound, a bound evaluated to NaN, or the lower bound is +inf / the upper bound is -inf. Unbounded variables (lower -inf, upper +inf) are allowed.
Fix
Ensure that for every element of the variable the evaluated lower bound is less than or equal to the upper bound, taking the instance data into account when the bounds are expressions.
