A graph structure restricts the set of possible coalitions of players, so that\nplayers are able to cooperate only if they are connected in the graph. Recently the average tree\nsolution has been proposed for arbitrary graph games by Herings et al. The average tree solution\nis the average of some specific marginal contribution vectors, and was shown to belong to the core\nif the game exhibits link-convexity. In this paper the main focus is placed on the relationship\nbetween the core and the average tree solution, and the following results were obtained. Firstly,\nit was shown that some marginal contribution vectors do not belong to the core even though the\ngame is link-convex. Secondly, an alternative condition to link-convexity was given. Thirdly, it\nwas proven that for cycle-complete graph games the average tree solution is an element of the\ncore if the game is link-convex.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_11_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"University of Tsukuba.
