Online Allocation and Pricing with Economies of Scale,fficiently produce such an allocation with cost at most a constant factor greater than the minimum over such allocations in hindsight, so long as the marginal costs do not decrease too rapidly. We also give a bicriteria approximation to social welfare for the case of more general valuation functions

Applications of ,-Strongly Regular Distributions to Bayesian Auctions,needed only to ensure good bounds on the expected revenue). In these cases we also investigate what happens when the distributions are known only approximately via samples, specifically how to modify the mechanisms so that they remain effective and how the expected revenue depends on the number of s

Elliot Anshelevich,Shreyas Sekarings. There were no fundamental changes but it was necessary to make some important modifications. To a certain extent, this statistical section has been shortened since, in the mean time, . (1966), and, independently, . (1966) and later . et al.

Nick Arnosti,Nicole Immorlica,Brendan Lucier Following in the footsteps of these critics, and acknowledging his debt to them, Erving Goffman has applied the concept to analysis of social behaviour.. Frame, therefore, is not a concept which is restricted to literature or even to art in general but is an abstract notion which refers to the comp
