A sequential convex semidefinite programming algorithm with an application to multiple-load free material optimization

M Stingl, M Kočvara, G Leugering - SIAM Journal on Optimization, 2009 - SIAM
A new method for the efficient solution of a class of convex semidefinite programming (SDP)
problems is introduced. The method extends the sequential convex programming (SCP) …

Sensing cox processes via posterior sampling and positive bases

M Mutný, A Krause - arXiv preprint arXiv:2110.11181, 2021 - arxiv.org

Superreplication of financial derivatives via convex programming

N Kahalé - Management Science, 2017 - pubsonline.informs.org
We give a method based on convex programming to calculate the optimal superreplicating
and subreplicating prices and corresponding hedging portfolios of a financial derivative in …

Can customer arrival rates be modelled by sine waves?

N Chen, R Gürlek, DKK Lee, H Shen - Service Science, 2024 - pubsonline.informs.org
Customer arrival patterns observed in the real world typically exhibit strong seasonal effects.
It is therefore natural to ask, can a nonhomogeneous Poisson process (NHPP) with a rate …

Bilinear optimality constraints for the cone of positive polynomials

G Rudolf, N Noyan, D Papp, F Alizadeh - Mathematical programming, 2011 - Springer
For a proper cone\mathcal K ⊂ R^ n and its dual cone\mathcal K^* the complementary
slackness condition ⟨\bf x,\bf s ⟩= 0 defines an n-dimensional manifold C (\mathcal K) in the …

Scalable dynamic bid prices for network revenue management in continuous time

SN Kirshner, M Nediak - Production and Operations …, 2015 - journals.sagepub.com
This study develops an approximate optimal control problem to produce time‐dependent bid
prices for the airline network revenue management problem. The main contributions of our …

Learning Generalization and Regularization of Nonhomogeneous Temporal Poisson Processes

SN Van, HN Xuan - arXiv preprint arXiv:2402.12808, 2024 - arxiv.org
The Poisson process, especially the nonhomogeneous Poisson process (NHPP), is an
essentially important counting process with numerous real-world applications. Up to date …
