Handling null values in constraints #324
Description
How do you handle variables that have "null" value, in constraint expressions. For example in Excel when we have an expression a*b + c, and b = empty, then Excel will just return c. How can we handle such expressions in SCIP constraints.
Another example is MAX(a,b,c) abd b is empty then it should return MAX(a,c)?
Looking forward to your advice.
