... • In a ring network with n nodes, a deletion of a single link (close to the sink) makes the algorithm reverse like crazy: Indeed a single link failure may start a reversal process that takes n rounds, and n links reverse themselves n2 times! • That’s why some researchers proposed partial link revers ...

... Each internal node x also contains x.n+1 pointers x.c1, x.c2, … x.cx.n+1 to its children. Leaf nodes have no children, and so their ci attributes are undefined. The keys x.keyi separate the ranges of keys stored in each subtree: if ki is any key stored in the subtree with root x.ci, then k1 <= x.key ...

Once we find the sum of a subset S’ is greater than t, we ignore that sum, as there is no reason to maintain it. No superset of S’ can possibly be ...
