Iterative Judgment Aggregation
  Judgment aggregation problems form a class of collective decision-making
problems represented in an abstract way, subsuming some well known problems
such as voting. A collective decision can be reached in many ways, but a direct
one-step aggregation of individual decisions is arguably most studied. Another
way to reach collective decisions is by iterative consensus building --
allowing each decision-maker to change their individual decision in response to
the choices of the other agents until a consensus is reached. Iterative
consensus building has so far only been studied for voting problems. Here we
propose an iterative judgment aggregation algorithm, based on movements in an
undirected graph, and we study for which instances it terminates with a
consensus. We also compare the computational complexity of our iterative
procedure with that of related judgment aggregation operators.
