 Envy-free item allocation

Envy-free item allocation is a concept in resource allocation and fair division, particularly in economics and game theory, where the goal is to distribute a set of items (or resources) among a group of individuals in such a way that no individual prefers the items allocated to someone else over their own. In other words, each participant feels satisfied with what they received and does not desire what others have, leading to a perception of fairness.
