Can Approximation Circumvent Gibbard-Satterthwaite?
The Gibbard-Satterthwaite Theorem asserts that any reasonable voting rule cannot be strategyproof. A large body of research in AI deals with circumventing this theorem via computa...

Where are the hard manipulation problems?
One possible escape from the Gibbard-Satterthwaite theorem is computational complexity. For example, it is NP-hard to compute if the STV rule can be manipulated. However, there is...

Average-case tractability of manipulation in voting via the fraction of manipulators
Recent results have established that a variety of voting rules are computationally hard to manipulate in the worst-case; this arguably provides some guarantee of resistance to man...

On The Complexity of Manipulating Elections
We study the manipulation of voting schemes, where a voter lies about their preferences in the hope of improving the election’s outcome. All voting schemes are potentially manip...
