What is another word for generalized duality?
Pronunciation: [d͡ʒˈɛnəɹə͡lˌa͡ɪzd djuːˈalɪti] (IPA) 
Generalized duality refers to the relationship between two mathematical optimization problems, which allows for a transformation of one problem into another. However, there are several synonyms for the term "generalized duality" which are commonly used in the field of mathematical optimization. These include "convex duality", which refers to the duality relationship between convex optimization problems, and "nonlinear duality", which refers to the duality relationship between nonlinear optimization problems. Other synonyms for generalized duality include "Lagrangian duality", "Fenchel duality", "optimality condition duality", and "perturbation analysis duality". Regardless of the terminology used, the concept of generalized duality provides powerful tools for solving complex optimization problems.
