Dear Markus,<br>
<br>
there is no such method in SCIP. The reason for this is, that in a
general CIP setting, there is no one-to-one correspondence between
constraints and rows. An "and" constraint, for example can add
multiple rows to get a tighter relaxation of the constraint in the
LP. The knapsack constraint handler, on the other hand, separates
knapsack cover cuts, so generates multiple rows as well, even if the
initial LP relaxation is just one row. Even more, a constraint
handler could also separate cuts based on more than one constraint
of its type.<br>
<br>
Therefore, there is no general method for this. "<a
moz-do-not-send="true">SCIPgetRowLinear</a>" is implemented in the
linear constraint handler, which knows at that point that it creates
exactly one row for each constraint and therefore can return the
row.<br>
<br>
What was it you wanted to do? Perhaps you can just work on the row
(you can get the columns there and also get the variable for a
column by "SCIPcolGetVar") or work directly on the linear
constraints?<br>
<br>

<div>Dear all,<br>
<br>
</div>
I have given a row in my LP which belongs to a linear
constraint. Now I am looking for a method which returns me
this linear constraint. <br>
I already have found the method "<a moz-do-not-send="true">SCIPgetRowLinear</a>".
In my understanding the other direction.<br>
