A unified approach to truthful scheduling on related machines
<12>This paper completely solves a well-known open problem, namely the existence of polynomial-time approximation schemes for truthful scheduling - a fundamental question in algorithmic game theory. This closes a long line of research started in FOCS'01, with intermediate results appearing in STACS'04, STACS'05, ESA'05, J. Discr. Alg.'09, FOCS'08 and SODA'10. This last paper resolved one important case, but the algorithm was highly complex and involved a lengthy and technical case analysis, making it very hard to follow and develop further. We provide a streamlined and generalized proof, which applies to a large set of objective functions including the makespan.
