Title:OptimalityConditionsofValueOptimizationProblemsintheEffectiveSense
Abstract:
Valueoptimizationproblemsarewidelyencounteredinvariousfields,fromengineeringandeconomicstomachinelearningandfinance.Theseproblemsinvolvefindingtheoptimalvaluesofdecisionvariablesthatmaximizeorminimizeanobjectivefunction,subjecttoasetofconstraints.Inthispaper,weinvestigatetheoptimalityconditionsofvalueoptimizationproblemsintheeffectivesense,focusingonnecessaryandsufficientconditionsfortheexistenceofaglobaloptimum.Wealsodiscusstheroleofconvexityandconvexoptimizationtechniquesinensuringoptimality.
