. ▁ ▁The ▁following ▁quote ▁el o qu ently ▁express es ▁Ben - Ha im ' s ▁assess ment ▁of ▁info - g ap ' s ▁relationship ▁to ▁Max imin ▁and ▁it ▁provides ▁am ple ▁motiv ation ▁for ▁the ▁analysis ▁that ▁follows . ▁We ▁note ▁that ▁robust ▁reli ability ▁is ▁em ph atically ▁ ▁not ▁ ▁a ▁worst - case ▁analysis . ▁In ▁classical ▁worst - case ▁min - max ▁analysis ▁the ▁designer ▁minim izes ▁the ▁impact ▁of ▁the ▁maxim ally ▁dam aging ▁case . ▁But ▁an ▁info - g ap ▁model ▁of ▁uncertainty ▁is ▁an ▁un bounded ▁family ▁of ▁nested ▁sets : ▁, ▁for ▁all ▁ ▁. ▁Con sequently , ▁there ▁is ▁no ▁worst ▁case : ▁any ▁ad verse ▁occurrence ▁is ▁less ▁dam aging ▁than ▁some ▁other ▁more ▁extreme ▁event ▁occurr ing ▁at ▁a ▁larger ▁value ▁of ▁. ▁What ▁Eq . ▁( 1 ) ▁express es ▁is ▁the ▁greatest ▁level ▁of ▁uncertainty ▁consistent ▁with ▁no - fail ure . ▁When ▁the ▁designer ▁cho oses ▁q ▁to ▁maxim ize ▁▁ ▁he ▁is ▁maxim izing ▁his ▁imm unity ▁to ▁an ▁un bounded ▁ambient ▁uncertainty . ▁The ▁closest ▁this ▁comes ▁to ▁" min - max ing " ▁is ▁that ▁the ▁design ▁is ▁chosen ▁so ▁that ▁" bad " ▁events ▁( ca using ▁reward ▁ ▁less ▁than ▁) ▁occur ▁as ▁" far ▁away " ▁as ▁possible ▁( be yond ▁a ▁maxim ized ▁value ▁of ▁ ▁). ▁ ▁Ben - Ha im , ▁ 1 9 9 9 , ▁pp .   2 7 1 – 2
