In routing games, the network performance at equilibrium can be significantly improved if we remove some edges from the network. This counterintuitive fact, a.k.a. Braess's paradox, gives rise to the network design problem, where we seek to recognize routing games suffering from the paradox, and to improve the equilibrium performance by edge removal. In this work, we investigate the computational complexity and the approximability of network design for non-atomic bottleneck routing games, where… 
Social Network Games with Obligatory Product Selection
TLDR
It is shown that social networks exist with the property that by adding an additional product to a specific node, the choices of the nodes will unavoidably evolve in such a way that everybody is strictly worse off.
Network Characterizations for Excluding Braess’s Paradox
TLDR
Under the model of nonatomic selfish routing, the topologies of k-commodity undirected and directed networks in which Braess’s paradox never occurs are characterized.
Excluding Braess's Paradox in Nonatomic Selfish Routing
TLDR
Under the model of nonatomic selfish routing, the topologies of k-commodity undirected and directed networks in which Braess’s paradox never occurs are characterized.
Paradoxes in social networks with multiple products
TLDR
It is shown that various paradoxes can arise in a natural class of social networks and these paradoxes shed light on possible inefficiencies arising when one modifies the sets of products available to the agents forming a social network or the network structure.

TLDR
It is proved that, for both splittable and unsplittable bottleneck games, there is a (not necessarily unique) Nash equilibrium, and the rate of convergence to a Nash equilibrium in each game is investigated.
The Hardness of Selective Network Design for Bottleneck Routing Games
TLDR
This paper considers selective network design on bottleneck routing games and assuming P ≠ NP the authors achieve the following results: for the unsplittable bottleneck games the trivial algorithm is a best possible approximation algorithm.

The Hardness of Network Design for Unsplittable Flow with Selfish Users
TLDR
It is shown that network design cannot improve the maximum possible bound on the price of anarchy in the worst case, and the trivial algorithm that builds the entire network is optimal for that case.
Efficient methods for selfish network design
TLDR
A polynomial-time algorithm that decides if a network is paradox-ridden, when latencies are linear and strictly increasing, and an algorithm for finding a subnetwork that is almost optimal wrt equilibrium latency, which outperforms any known approximation algorithm for the case of strictly increasing linear latencies.
Resolving Braess's Paradox in Random Networks
Braess's paradox states that removing a part of a network may improve the players' latency at equilibrium. In this work, we study the approximability of the best subnetwork problem for the class of
Network Load Games
TLDR
This work presents results related to the existence, complexity, and price of anarchy of Pure Nash Equilibria for several network load games, a class of routing games in networks which generalize selfish routing games on networks consisting of parallel links.
Bottleneck links, variable demand, and the tragedy of the commons
TLDR
The study of the price of anarchy with variable demand and with broad classes of nonlinear aggregation functions is initiated, focusing on selfish routing in single- and multicommodity networks, and on the lp norms for 1 ≤ p ≤ ∞; the main results are as follows.
Braess's Paradox, Fibonacci Numbers, and Exponential Inapproximability
TLDR
An infinite family of two-commodity networks, related to the Fibonacci numbers, in which both of these quantities grow exponentially with the size of the network, and an exponential upper bound on the worst-possible severity of Braess’s Paradox and on the price of anarchy for the maximum latency.
