We take a unifying approach to single selection optimal stopping problems with random arrival order and independent sampling of items. In the problem we consider, a decision maker (DM) initially gets to sample each of $N$ items independently with pro

In “School Choice in Chile,” Correa et al. describe the design and implementation of the new school admissions system in Chile. The design, based on the celebrated work of Gale, Shapley, and Roth, involves several challenges to comply with the Ch

The results are presented for the initial form stability analysis of the optimal aerodynamic design algorithm in context of an isolated three-dimensional wing of a wide-body long-range aircraft. The solution to the problem of geometry determination w

A robust and accurate method for aerodynamic shape optimization, previously developed by the authors, is extended to automatic multipoint design of aircraft configurations with under-the-wing-mounted nacelle. The shape is optimized for minimum drag a

A computational-fluid-dynamics-driven robust and accurate method for aerodynamic shape optimization, previously developed by the authors, is further enhanced by extending it to automatic multipoint design of wing–body–nacelle configurations. The

This paper handles the problem of accuracy loss for flow solutions on computational domains with a heterogeneous discretization on the subdomains. The problem occurs, e.g., when a composite multiblock mesh comprises blocks with different grid resolut

The main goal of this paper is to document a comparative study of different computational-fluid-dynamics-based optimization techniques applied to the solution of a three-dimensional wing drag minimization problem. To achieve this objective, three opt
