Secretary Problems with Convex Costsunder various feasibility constraints and present online algorithms with competitive ratios only a constant factor worse than those known in the absence of costs for the same feasibility constraints. We also consider a multi-dimensional version of the problem that generalizes multi-dimensional knaps

Nearly Simultaneously Resettable Black-Box Zero Knowledgeumber of times. The main contribution of our construction is that the round complexity is independent of the above bound. To achieve our result, we construct a constant-round nearly simultaneously resettable coin-flipping protocol that we believe is of independent interest.

Approximation Algorithms for Online Weighted Rank Function Maximization under Matroid Constraintsime. This problem is a natural extension of two well-studied streams of earlier work: the first is on online set cover algorithms (in particular for the max coverage version) while the second is on approximately maximizing submodular functions under a matroid constraint..In this paper, we present th

Using this, we obtain an . approximation algorithm for QP-ratio. We also give a . approximation for bipa
