A note on self-improving sorting with hidden partitions

Siu-Wing Cheng, Man-Kwun Chiu, Kai Jin

We study self-improving sorting with hidden partitions. Our result is an optimal algorithm which runs in expected time O(H(π(I)) + n), where I is the given input which contains n e…

On the Turaev genus of torus knots

Kaitian Jin, Adam M. Lowrance, Eli Polston +1

The Turaev genus and dealternating number of a link are two invariants that measure how far away a link is from alternating. We determine the Turaev genus of a torus knot with five…

On the power of dominated players in team competitions

Kai Jin, Pingzhong Tang, Shiteng Chen

We investigate multi-round team competitions between two teams, where each team selects one of its players simultaneously in each round and each player can play at most once. The c…
