Altruism in Atomic Congestion Gameslfish and social objectives. In particular, we assume agents optimize a linear combination of personal delay of a strategy and the resulting social cost. Stable states are the Nash equilibria of these games, and we examine their existence and the convergence of sequential best-response dynamics. For

Geometric Spanners for Weighted Point Setsdistance function .., where ..(.,.) is w(.) + .(.,.) + . if . ≠ . and 0 otherwise. We present a general method for turning spanners with respect to the .-metric into spanners with respect to the ..-metric. For any given .> 0, we can apply our method to obtain (5 + .)-spanners with a linear number of

-Outerplanar Graphs, Planar Duality, and Low Stretch Spanning Treese approximating trees are required to be (subgraph) spanning trees of the given graph (or multigraph), in which case, the focus is usually on the equivalent problem of finding a (single) tree with low average stretch. Among the classes of graphs that received special attention in this context are .-

Narrow-Shallow-Low-Light Trees with and without Steiner Points Moreover, for every point ., the distance between . and . in . is within a factor of (1 + .) close to their Euclidean distance ||.,.||. We call these trees . (NSLLTs). We demonstrate that our construction achieves optimal (up to constant factors) tradeoffs between . parameters of NSLLTs. Our constr

This stands in contrast to the results for the analogous special case in the first-price model, the standard bipartit

,Die selektive Erdschlußbekämpfung,ilibrium and any better-response dynamics converges. In addition, we consider a scenario in which a central altruistic institution can motivate agents to act altruistically. We provide constructive and hardness results for finding the minimum number of altruists to stabilize an optimal congestion pr
