Reproducibility Variable Result LLM Response
Research Type Theoretical In this paper, we introduce and study a formal model for such scenarios. Specifically, we consider the problem of fair allocation of indivisible items in settings where there is a graph capturing the dependency relation between items, and each agent s share has to be connected in this graph. We prove a strong positive result for our setting: an MMS allocation always exists if the underlying graph is a tree, and can be computed efficiently. Our algorithm is an adaptation of the classic last-diminisher procedure for the divisible case. In contrast, we provide an example where the underlying graph is a cycle of length 8 and there is no MMS allocation.
