Core (game theory)
open-in-new
<p>In <a href="/facts/Cooperative_game_theory/L2KfzepP">cooperative game theory</a>, the core is the <a href="/facts/Set_(mathematics)/BfucfHMq">set</a> of <a href="/facts/Feasible_region/cJUKNCmM">feasible</a> allocations or <a href="/facts/Imputation_(game_theory)/wskcaQ6o">imputations</a> where no coalition of agents can benefit by breaking away from the grand coalition. </p><p>An allocation is said[<i>by whom?</i>] to be in the <i>core</i> of a game if there is no coalition that can improve upon it. The core is then the set of all feasible allocations. </p>
