In the Approval Participatory Budgeting problem an agent prefers a set of projects $W$ over $W$ if she approves strictly more projects in $W$. A set of projects $W$ is in the core, if there is no other set of projects $W$ and set of agents $K$ that both prefer $W$ over $W$ and can fund $W$. It is an open problem whether the core can be empty, even when project costs are uniform. the latter case is known as the multiwinner voting core. We show that in any instance with uniform costs or with at most four projects (and any number of agents), the core is nonempty.
Participatory budgeting is a democratic process for allocating funds to projects based on the votes of members of the community. However, most input methods of voters preferences prevent the voters from expressing complex relationships among projects
Participatory budgeting (PB) is a democratic process where citizens jointly decide on how to allocate public funds to indivisible projects. This paper focuses on PB processes where citizens may give additional money to projects they want to see funde
In participatory budgeting, communities collectively decide on the allocation of public tax dollars for local public projects. In this work, we consider the question of fairly aggregating the preferences of community members to determine an allocatio
We address the question of aggregating the preferences of voters in the context of participatory budgeting. We scrutinize the voting method currently used in practice, underline its drawbacks, and introduce a novel scheme tailored to this setting, wh
To choose a suitable multiwinner voting rule is a hard and ambiguous task. Depending on the context, it varies widely what constitutes the choice of an ``optimal subset of alternatives. In this paper, we provide a quantitative analysis of multiwinner
