Reproducibility Variable Result LLM Response
Research Type Theoretical We first show that... an individually stable and justified envy-free partition may not exist and deciding its existence is NPcomplete. Then, we prove that the top responsiveness property guarantees the existence of a Pareto optimal, individually stable, and envy-free partition, but it is not sufficient for the conjunction of core stability and envy-freeness. Finally, under bottom responsiveness, we show that deciding the existence of an individually stable and envy-free partition is NP-complete, but a Pareto optimal and justified envy-free partition always exists.
