Minimizing Congestion in General Networks
A principle task in parallel and distributed systems is to reduce the communication load in the interconnection network, as this is usually the major bottleneck for the performanc...

Logarithmic hardness of the directed congestion minimization problem
We show that for any constant ε > 0, there is no Ω(log1−ε M)approximation algorithm for the directed congestion minimization problem on networks of size M unless NP ⊆ Z...

Quorum placement in networks: minimizing network congestion
A quorum system over a universe of logical elements is a collection of subsets (quorums) of elements, any two of which intersect. In numerous distributed algorithms, the elements ...

Tolls for Heterogeneous Selfish Users in Multicommodity Networks and Generalized Congestion Games
We prove the existence of tolls to induce multicommodity, heterogeneous network users that independently choose routes minimizing their own linear function of tolls versus latency...

On the behavior of congestion minimization during placement
Typical placement objectives involve reducing net-cut cost or minimizing wirelength. Congestion minimization is least understood, however, it models routability accurately. In thi...
