We present the zipper tree, the first O(log log n)-competitive online binary search tree that performs each access in O(log n) worst-case time. This shows that for binary search ...
This paper presents an O(n2 ) algorithm for deciding isomorphism of graphs that have bounded feedback vertex set number. This number is defined as the minimum number of vertex de...
We attend to the classic setting where an observer needs to inform a tracker about an arbitrary time varying function f : N0 → Z. This is an optimization problem, where both wron...
