, ▁the ▁" rob ust ness " ▁of ▁a ▁decision ▁is ▁set ▁by ▁the ▁size ▁of ▁deviation ▁from ▁an ▁estimate ▁that ▁still ▁leads ▁to ▁performance ▁within ▁requirements ▁when ▁using ▁that ▁decision . ▁It ▁is ▁sometimes ▁difficult ▁to ▁judge ▁how ▁much ▁robust ness ▁is ▁needed ▁or ▁sufficient . ▁However , ▁according ▁to ▁info - g ap ▁theory , ▁ ▁the ▁ranking ▁of ▁feas ible ▁dec isions ▁in ▁terms ▁of ▁their ▁degree ▁of ▁robust ness ▁is ▁independent ▁of ▁such ▁jud g ments . ▁ ▁Info - g ap ▁theory ▁also ▁propos es ▁an ▁opportun eness ▁function ▁which ▁evalu ates ▁the ▁potential ▁for ▁wind fall ▁out comes ▁resulting ▁from ▁favor able ▁uncertainty . ▁ ▁Example : ▁resource ▁allocation ▁ ▁Here ▁is ▁an ▁illustr ative ▁example , ▁which ▁will ▁introduce ▁the ▁basic ▁concepts ▁of ▁information ▁gap ▁theory . ▁More ▁rig orous ▁description ▁and ▁discussion ▁follows . ▁ ▁Resource ▁allocation ▁Suppose ▁you ▁are ▁a ▁project ▁manager , ▁super vis ing ▁two ▁teams : ▁red ▁team ▁and ▁blue ▁team . ▁Each ▁of ▁the ▁teams ▁will ▁yield ▁some ▁re venue ▁at ▁the ▁end ▁of ▁the ▁year . ▁This ▁re venue ▁depends ▁on ▁the ▁invest ment ▁in ▁the ▁team ▁– ▁higher ▁invest ments ▁will ▁yield ▁higher ▁reven ues . ▁You ▁have ▁a ▁limited ▁amount ▁of ▁resources , ▁and ▁you ▁wish ▁to ▁decide ▁how ▁to ▁allocate ▁these ▁resources ▁between ▁the ▁two ▁groups , ▁so ▁that ▁the ▁total ▁reven ues ▁of ▁the ▁project ▁will ▁be ▁as ▁high ▁as ▁possible . ▁ ▁If ▁you ▁have ▁an ▁estimate ▁of ▁the ▁correlation ▁between ▁the ▁invest ment
