 == BOA
-Boa (Bidding, Opponent Model, Acceptance Model) is an attempt to split negotiation into three basic components: modeling the opponent's profile, determining a proper next action and determining when to accept [https://homepages.cwi.nl/~baarslag/pub/Decoupling_Negotiating_Agents_to_Explore_the_Space_of_Negotiation_Strategies_ACAN_2012.pdf see paper]. The boa module allows parties to be written with this and provides example implementations of the components.
-
-WARNING: The current design of BOA Components makes it possible to create circular dependencies between the components. This will result in a deadlock of parties using that component. Currently the plan is that the component interface will be changed in the future to prevent this.

 Action getAction(BoaState state);

+Technically, the Bidding Strategy can return other actions, eg EndNegotiation or Accept. However the intention of the Bidding Strategy is that Offers are returned; the AcceptanceStrategy will then replace Offers with Accepts if accepting is more appropriate.
