A Greuet, M Safey El Din - SIAM Journal on Optimization, 2014 - SIAM
Let f,f_1,...,f_s be n-variate polynomials with rational coefficients of maximum degree D and
let V be the set of common complex solutions of F=(f_1,...,f_s). We give an algorithm which …

Tight relaxations for polynomial optimization and Lagrange multiplier expressions

This paper proposes tight semidefinite relaxations for polynomial optimization. The
optimality conditions are investigated. We show that generally Lagrange multipliers can be …

A Correlatively Sparse Lagrange Multiplier Expression Relaxation for Polynomial Optimization

Z Qu, X Tang - SIAM Journal on Optimization, 2024 - SIAM
In this paper, we consider polynomial optimization with correlative sparsity. We construct
correlatively sparse Lagrange multiplier expressions (CS-LMEs) and propose CS-LME …

Positivity certificates and polynomial optimization on non-compact semialgebraic sets

NHA Mai, JB Lasserre, V Magron - Mathematical Programming, 2022 - Springer
In a first contribution, we revisit two certificates of positivity on (possibly non-compact) basic
semialgebraic sets due to Putinar and Vasilescu (CR Acad Sci Ser I Math 328 (6): 495–499 …
