Comment (by dcoudert):
The "cuts+" algorithm is an approximation algorithm with additive constant
one (ALG <= OPT <= ALG+1). Therefore, additive/multiplicative approx
factors are irrelevant in this case.
However, these parameters are still used with the "cuts" version.
We could may be combine additive approx with "cuts+", for instance asking
for "2*(additive_gap-1)". I'm not sure it is really interesting.
Does it make more sense?
