Strategic Contention Resolution in Multiple Channelstrategic contention resolution examine only the case of a single channel and show that the equilibrium protocols depend on the feedback that the communication system gives to the players. Here we present multi-channel equilibrium protocols in two main feedback classes, namely . and .. In particular,

Bin Packing Games with Weight Decision: How to Get a Small Value for the Price of Anarchyase of the game where the weight of any item is the same as its size, and any item has size at most one half. The previous bound was about 1.46457. Next we give another setting where the PoA is at most .. This value is better than any previous, that was got for such games.

Probabilistic Embeddings of the Fréchet Distanceinary experimental results stand in stark contrast with our lower bounds. They indicate that highly distorted projections happen very rarely in practice, and only for strongly conditioned input curves.

For the lower bounds, we prove that (i) there is a set of sequences, such that on a sequence picked randomly from this set every algorithm must return an .-approximation with high probability, and (ii)

Finally, we apply the template to obtain lower bounds for a number of standard discrete optimization problems.
