Several books have recently been published describing applications of the theory of conjugate convex functions to duality in problems of optimization.

The finite-dimensional case has been treated by Conjugate Duality in Convex Optimization book and Witzgall [25] and Rockafellar [13] and the infinite-dimensional case. In mathematics and mathematical optimization, the convex conjugate of a function is a generalization of the Conjugate Duality in Convex Optimization book transformation which applies to non-convex functions.

It is also known as Legendre–Fenchel transformation or Fenchel transformation (after Adrien-Marie Legendre and Werner Fenchel).It allows in particular for a far reaching generalization of Lagrangian duality.

convex optimization, i.e., to develop the skills and background needed to recognize, formulate, and solve convex optimization problems. Developing a working knowledge of convex optimization can be mathematically demanding, especially for the reader interested primarily in applications.

In our. We study conjugate duality with arbitrary coupling functions. Our only tool is a certain support property, which is automatically fulfilled in the two most widely used special cases, namely the case where the underlying space is a topological vector space and the coupling functions are the continuous linear ones, and the case where the underlying space is a metric space and the coupling Cited by: Buy Conjugate Duality and Optimization This monograph presents an excellent introduction to convex duality.

If you want to understand duality via perturbations and its connection to lagrangian functions this is a great way to start.

as a supplement to the book. The results presented in this book originate from the last decade research work of the author in the?eld of duality theory in convex optimization.

The reputation of duality in the optimization theory comes mainly from the major role that it plays in formulating necessary and suf?cient optimality conditions and, consequently, in Book Edition: Ed. This book presents fundamentals and comprehensive results regarding duality for scalar, vector and set-valued optimization problems in a general setting.

After a preliminary chapter dedicated to convex analysis and minimality notions of sets with respect to partial orderings induced by convex cones a chapter on scalar conjugate duality follows.

This book presents new achievements and results in the theory of conjugate duality for convex optimization problems. The perturbation approach for attaching a dual problem to a primal one makes the object of a preliminary chapter, where also an overview of the classical generalized interior point regularity conditions is Edition: Equivalence between a constrained scalar optimization problem and its three conjugate dual models is established for the class of generalized C-subconvex functions.

Applying these equivalent relations, optimality conditions in terms of conjugate functions are obtained for the constrained multiobjective optimization by: 1.

The results presented in this book originate from the last. Australia’s leading bookseller for years. Recently as I was reading Optimization by vector space methods, I noticed that in Sectionin order to prove the Lagrange duality theorem, the book introduces another dual functional: $$\textsf{inf}_{x}\{f(x)+ \langle x^*, x\rangle\}$$ The book claims that those two definitions are essentially the same.

I can see that they have the same. Weak duality and strong duality weak duality: d∗ ≤ p∗ always holds (for convex and nonconvex problems) can be used to ﬁnd nontrivial lower bounds for diﬃcult problems, e.g., solving the SDP max ν −1Tν s.t. W +diag(ν) 0 gives a lower bound for the two-way partitioning File Size: KB.
