This is the third time I review a paper. I find one problem in academia very distasteful. Many people work on the same problem for many years, with each publication justified by just an epsilon improvement. Of course, they can justify such approach as conducting a focused research with a strong theme. It is just not my taste: how boring the life would be!

The paper I am reviewing falls in this category. The original paper solve an interesting convex optimization problem decently:
min_{x,y} f(x,y) s.t. x+yle C. The following up paper, however, simply replaces the constraint with a convex term in the objective function: min_{x,y} f(x,y) + a(x+y-C)^+. What a boring paper:(
