[Scip] Is it possible to change the coefficient of a variable in a SCIP_ROW?

[nikolaj@crt.umontreal.ca]

Dear SCIPpers,

In my branch, price and cut, the generation of a new variable could ask
for the change in coefficient for few variables in a SCIP_ROW (i.e. the
cut would be stronger if reinterpreted in another way).

Is it possible to change the coefficient of a variable in a SCIP_ROW?

If yes, how can I do that?

If not, how can I replace the still active cut by the new one? Should I
use SCIPdelPoolCut to remove the old one?

Have a nice day,

Nikolaj
