Thinner is not always better: Cascade knapsack problems
In the context of branch-and-bound (B&B) for integer programming (IP) problems, a direction along which the polyhedron of the IP has minimum width is termed a thin direction. We demonstrate that a thin direction need not always be a good direction to branch on for solving the problem efficiently. Further, the integer width, which is the number of B&B nodes created when branching on the directio...

متن کاملFor telomeres, longer is not always better.
N E W S " Short people got no reason to live, " goes the Randy Newman song. The same used to be thought of cells with short telomeres, those indispensable nubs of repetitive DNA and protein coating that protect the ends of chromosomes. But if Randy Newman was singing about telomeres, he would have to rewrite his lyrics. New findings are overturning what scientists thought they knew about the im...
متن کاملIs more always better
Is more always better? We address this question in the context of bibliometric indices that aim to assess the scientific impact of individual researchers by counting their number of highly cited publications. We propose a simple model in which the number of citations of a publication depends not only on the scientific impact of the publication but also on other ‘random’ factors. Our model indic...
