This manuscript presents an alternative implementation of the truthful-in-expectation mechanism of Dughmi, Roughgarden and Yan for combinatorial auctions with weighted-matroid-rank-sum valuations. The new implementation uses only value queries and is approximately truthful-in-expectation, in the sense that by reporting truthfully each agent maximizes his utility within a multiplicative 1-o(1) factor. It still provides an optimal (1-1/e-o(1))-approximation in social welfare. We achieve this by…
A Truthful-in-Expectation Mechanism for the Generalized Assignment Problem

This work presents a novel convex optimization program for the auction which results in a maximal-in-distributional-range (MIDR) allocation rule and simplifies the existing optimization algorithms for the GAP while the approximation ratio is comparable to the best given approximation.

It is proved that there is a constant \gamma>0 such that there are no truthful-in-expectation mechanisms that achieves an m-\gamma-approximation to the optimal social welfare for combinatorial public projects with sub modular valuations in the value oracle model.

A truthful-in-expectation, (1-1/e)-approximation mechanism for a strategic variant of the generalized assignment problem (GAP), which improves upon the existing optimization algorithms for GAP in terms of simplicity and runtime while the approximation ratio closely matches the best approximation ratio known for G AP when all inputs are publicly known.

Application of multiplicative weights update method in algorithmic game theory
A randomized algorithm for computing an approximate saddle point, or equivalently equilibrium, for a convex-concave functions F : X × Y → R, where X and Y are convex sets of arbitrary dimensions is designed, based on a technique developed by Grigoriadis and Khachiyan.
Mechanisms for Risk Averse Agents, Without Loss

It is shown that any truthful-in-expectation mechanism can be generically transformed into a mechanism that is incentive compatible even when agents are risk averse, without modifying the mechanism's allocation rule.
Low-Risk Mechanisms for the Kidney Exchange Game

A $2-approximation randomized truthful mechanism in which the variance of the utility of each agent is at most$2+\epsilon\$ and can be used to design low risk or almost truthful mechanisms for other problems.

This work proposes to use the much simpler and usually faster multiplicative weights update method instead of the Ellipsoid method, which comes at the cost of slightly weaker approximation and truthfulness guarantees.

In this paper we consider the pairwise kidney exchange game. This game naturally appears in situations that some service providers benefit from pairwise allocations on a network, such as the kidney

Optimal approximation for the submodular welfare problem in the value oracle model
A randomized continuous greedy algorithm is developed which achieves a (1-1/e)-approximation for the Submodular Welfare Problem in the value oracle model and is shown to have a potential of wider applicability on the examples of the Generalized Assignment Problem and the AdWords Assignment Problem.

The main result is that for any fixed instance that exhibits a certain "symmetry gap" in its multilinear relaxation, there is a naturally related class of instances for which a better approximation factor than the symmetry gap would require exponentially many oracle queries, and this unifies several known hardness results for submodular maximization.
