• Abstract: We examine an approval-based model of Liquid Democracy with a budget constraint on voting and delegating costs, aiming to centrally select casting voters ensuring complete representation of the electorate. From a computational complexity perspective, we focus on minimizing overall costs, maintaining short delegation paths, and preventing excessive concentration of voting power. Furthermore, we explore computational aspects of strategic control, specifically, whether external agents can change election components to influence the voting power of certain voters.

• Efficient Lower Bounding of Single Transferable Vote Election Margins [56.12949230611067]
  Single transferable vote (STV) is a system of preferential proportional voting employed in multi-seat elections. The margin of victory, or simply margin, is the smallest number of ballots that, if manipulated, can alter the set of winners. Lower bounds on the margin can also be used for this purpose, in cases where exact margins are difficult to compute.

• Optimal bounds for dissatisfaction in perpetual voting [84.02572742131521]
  We consider a perpetual approval voting method that guarantees that no voter is dissatisfied too many times. We identify a sufficient condition on voter behavior under which a sublinear growth of dissatisfaction is possible. We present a voting method with sublinear guarantees on dissatisfaction under bounded conflicts, based on the standard techniques from prediction with expert advice.

  We study the problem of designing publicly auditable yet privacy-preserving electoral rolls. The audit can detect polling-day ballot stuffing and denials to eligible voters by malicious polling officers. The entire electoral roll is never revealed, which prevents any large-scale systematic voter targeting and manipulation.

  Risk-limiting audits (RLAs) are techniques for verifying the outcomes of large elections. We define new families of audits that improve efficiency and offer advances in statistical power. New audits are enabled by revisiting the standard notion of a cast-vote record so that it can declare multiple possible mark interpretations.

  The Stanford Participatory Budgeting platform has been used to engage residents in more than 150 budgeting processes. We present a data set with anonymized budget opinions from these processes with K-approval, K-ranking or knapsack primary ballots. We use vote pairs with different voting methods to analyze the effect of voting methods on the cost of selected projects.

  Methods for auditing instant-runoff voting (IRV) elections are either not risk-limiting or require cast vote records (CVRs), the voting system's electronic record of the votes on each ballot. We develop an RLA method that uses adaptively weighted averages of test supermartingales to efficiently audit IRV elections when CVRs are not available.

  One of the main challenges in e-voting systems is to certify that the computed results are consistent with the cast ballots. We propose a secure voting protocol for elections governed by order-based voting rules. Our protocol offers perfect ballot secrecy, in the sense that it issues only the required output, while no other information on the cast ballots is revealed.

  We study the problem of bribery in multiwinner elections, for the case where the voters cast approval ballots (i.e., sets of candidates they approve) We consider a number of approval-based multiwinner rules (AV, SAV, GAV, RAV, approval-based Chamberlin--Courant, and PAV) In general, our problems tend to be easier when we limit out bribery actions on increasing the number of approvals of the candidate that we want to be in a winning committee.
