public default UtilityTable queryUtil ( BNetwork network , String queryVar ) { return queryUtil ( new Query . UtilQuery ( network , Arrays . asList ( queryVar ) , new Assignment ( ) ) ) ; }
computes the utility table for the query variable ( typically an action variable ) , assuming no additional evidence .
