LIGHTWEIGHT DESIGN OF STRUCTURES BASED ON A SEMIDEFINITE PROGRAMMING METHOD (MT)
Jixie qiangdu, 2022 A semidefinite programming-based optimization method is proposed for lightweight design of boom and stay bars of container cranes. The boom and stay bars are welded together by steel plates, and in engineering practices the cross-sectional dimensions of ...

American Journal of Agricultural Economics, EarlyView.Abstract Alcohol policy liberalization is a contentious issue in the United States, including debates over whether grocery stores should be allowed to sell wine. This issue reflects a dilemma between accommodating consumer convenience, promoting wine industry growth, and generating tax revenue, versus concerns about potential harm to liquor stores ...

Linear semidefinite programming problems: regularisation and strong dual formulations
Журнал Белорусского государственного университета: Математика, информатика, 2020 Regularisation consists in reducing a given optimisation problem to an equivalent form where certain regularity conditions, which guarantee the strong duality, are fulfilled.

Cubical coloring — fractional covering by cuts and semidefinite programming [PDF]
Discrete Mathematics & Theoretical Computer Science, 2015 We introduce a new graph parameter that measures fractional covering of a graph by cuts. Besides being interesting in its own right, it is useful for study of homomorphisms and tension-continuous mappings.

Quantum Coding via Semidefinite Programming
2019 IEEE International Symposium on Information Theory (ISIT), 2019 We derive converging hierarchies of efficiently computable semidefinite programming outer bounds on the optimal fidelity for the transmission of quantum information over noisy quantum channels. Based on positive partial transpose conditions we give a sufficient criterion for the exact convergence at any given level of the hierarchies.

Computing Skinning Weights via Convex Duality
Computer Graphics Forum, EarlyView.We present an alternate optimization method to compute bounded biharmonic skinning weights. Our method relies on a dual formulation, which can be optimized with a nonnegative linear least squares setup. Abstract We study the problem of optimising for skinning weights through the lens of convex duality.

A Method for Semidefinite Quasiconvex Maximization Problem
Известия Иркутского государственного университета: Серия "Математика", 2016 We introduce so-called semidefinite quasiconvex maximization problem. We derive new global optimality conditions by generalizing [9]. Using these conditions, we construct an algorithm which generates a sequence of local maximizers that converges to a ...
