802.16 networks was conducted in [7], [8] by combining link-layer queueing with physical-layer transmission. A vacation queueing model was adopted in [9] to analyze the link-layer queueing performance of OFDM-TDMA systems with round-robin scheduling. A queueing model for OFDMA systems was used in [10] to design a scheduling scheme that balances

MapReduce clusters, web-servers, hospitals, call-centers and airport passenger terminals. To model such systems accurately we must infer queueing parameters from data. Unfor-tunately, for many queueing networks there is no clear way to proceed with parameter inference from data. Approximate Bayesian computation could o er a straight-forward

In these notes we focus on algorithmic game theory, a relatively new field that lies in the intersection of game theory and computer science. The main objective of algorithmic game theory is to design effective algorithms in strategic environments. In the first part of these notes, we focus on algorithmic theory's earliest research goals—
