On Short Fastest Paths in Temporal Graphs..The dominance relation is interesting in its own right, and may be of use for several related problems like fastest paths with minimum fare, fastest paths with minimum number of stops, and other pareto-optimal path problems in temporal graphs.

The Bike Sharing Probleme end of the interval..Our main result is the construction of a polynomial time algorithm for the Bike Sharing problem that creates an arrival-time optimal schedule for travellers and bikes to travel across the interval. For the Relaxed Bike Sharing problem, we give an algorithm that gives an optima

Efficient Generation of a Card-Based Uniformly Distributed Random Derangementf approximately 0.6. In this study, we consider how to decrease the probability of the need to restart the shuffle based on the aforementioned protocol. Specifically, we prepare more piles of cards than the number . of players. This potentially helps us avoid repeating the shuffle, because we can re
