 *         This is the decoupled Acceptance Conditions from the Gahboninho
 *         (ANAC2011). The code was taken from the ANAC2011 Gahboninho and
 *         adapted to work within the BOA framework.

 * 
 *         BUG In the original version the opponent model is only updated once,
 *         which is good for the performance of the agent, as the model is very
