Strong and Weak Convexity of Sets and Functions
TL;DR: This paper studies two classes of sets, strongly and weakly convex sets, and studies a class of functions, denoted (rho)-convex, which satisfy for arbitrary points x 1 and x 2 and any value (lambda) [0, 1] the classical inequality of convex functions up to a term.
Journal ArticleDOI
Retailer-Supplier Flexible Commitments Contracts: A Robust Optimization Approach
TL;DR: This work studies a two-echelon multiperiod supply chain problem, known as the retailer-supplier flexible commitment (RSFC) problem with uncertain demand that is only known to reside in some uncertainty set and adopts a min-max criterion.

Convex nondifferentiable optimization: A survey focused on the analytic center cutting plane method
TL;DR: A self-contained convergence analysis that uses the formalism of the theory of self-concordant functions, but for the main results, direct proofs based on the properties of the logarithmic function are given.
