▁by ▁construction , ▁for ▁any ▁triple t ▁ ▁of ▁interest ▁we ▁have ▁ ▁This ▁means ▁that ▁in ▁the ▁case ▁of ▁robust ness / Max imin , ▁an ▁ant agon istic ▁Nature ▁will ▁( effect ively ) ▁minim ize ▁ ▁by ▁minim izing ▁▁ ▁whereas ▁in ▁the ▁case ▁of ▁ ▁opportun eness / Min imin ▁a ▁sympath etic ▁Nature ▁will ▁( effect ively ) ▁maxim ize ▁ ▁by ▁minim izing ▁. ▁ ▁Sum mary ▁▁ ▁Info - g ap ' s ▁robust ness ▁analysis ▁st ip ul ates ▁that ▁given ▁a ▁pair ▁, ▁the ▁worst ▁element ▁of ▁ ▁is ▁realized . ▁This ▁of ▁course ▁is ▁a ▁typical ▁Max imin ▁analysis . ▁In ▁the ▁parl ance ▁of ▁classical ▁decision ▁theory : ▁The ▁Rob ust ness ▁of ▁decision ▁ ▁is ▁the ▁largest ▁horizon ▁of ▁uncertainty , ▁, ▁ ▁such ▁that ▁the ▁worst ▁value ▁of ▁ ▁in ▁ ▁satisfies ▁the ▁performance ▁requirement ▁. ▁▁▁ ▁Similarly , ▁info - g ap ' s ▁opportun eness ▁analysis ▁st ip ul ates ▁that ▁given ▁a ▁pair ▁, ▁the ▁best ▁element ▁of ▁ ▁is ▁realized . ▁This ▁of ▁course ▁is ▁a ▁typical ▁Min imin ▁analysis . ▁In ▁the ▁parl ance ▁of ▁classical ▁decision ▁theory : ▁The ▁O pport un eness ▁of ▁decision ▁▁ ▁is ▁the ▁smallest ▁horizon ▁of ▁uncertainty , ▁ ▁, ▁ ▁such ▁that ▁the ▁best ▁value ▁of ▁ ▁in ▁ ▁satisfies ▁the ▁performance ▁requirement ▁. ▁▁▁ ▁The ▁mathematical ▁transl iter ations ▁of ▁these ▁concepts ▁are ▁straightforward , ▁resulting ▁in ▁typical ▁Max imin / Min imin ▁models , ▁respectively .
