DronesThis paper studies energy-aware trajectory generation for the gate-passage maneuver of a multirotor-slung load system with a varying-length cable. The mission requires load and drone gate clearance while enforcing positive cable tension and recovered ...

Medial Axis Aware Learning of Signed Distance Functions
Computer Graphics Forum, EarlyView.Abstract We propose a novel variational method to compute a highly accurate global signed distance function (SDF) to a given point cloud. To this end, the jump set of the gradient of the SDF, which coincides with the medial axis of the surface, is explicitly taken into account through a higher‐order variational formulation that enforces linear growth ...

A Quantile Model of Firm Investment
International Economic Review, EarlyView.ABSTRACT Are firms risk averse? We propose a dynamic model of firm investment under uncertainty that captures firms' risk attitudes through quantile preferences. The firm maximizes its present value, defined as current profits and investment plus the discounted value of the τ$\tau$‐quantile of its value next period.

Hidden Convexity in Partially Separable Optimization [PDF]
The paper identifies classes of nonconvex optimization problems whose convex relaxations have optimal solutions which at the same time are global optimal solutions of the original nonconvex problems. Such a hidden convexity property was so far limited to

Generalized S-Lemma and strong duality in nonconvex quadratic programming
, 2013 On the basis of a new topological minimax theorem, a simple and unified approach is developed to Lagrange duality in nonconvex quadratic programming.

A Global Optimality Criterion for Nonconvex Quadratic Programming over a Simplex
, 2005 In this paper we propose a global optimality criterion for globally minimizing a quadratic form over the standard simplex, which in addition provides a sharp lower bound for the optimal value. The approach is based on the solution of a semidefinite program (SDP) and a convex quadratic program (QP).

Assessing second‐price auctions for parcel exchanges in last‐mile logistics
International Transactions in Operational Research, Volume 34, Issue 2, Page 1040-1071, March 2027.Abstract The rapid growth of e‐commerce has led to multiple carriers operating in the same regions, creating opportunities for collaboration. However, logistics companies typically operate independently, leading to inefficiencies. Horizontal cooperation, where carriers share resources and infrastructure, can improve efficiency and reduce costs.

The Complexity of Optimizing over a Simplex, Hypercube or Sphere: A Short Survey [PDF]
We consider the computational complexity of optimizing various classes of continuous functions over a simplex, hypercube or sphere.These relatively simple optimization problems have many applications.We review known approximation results as well as ...

Oligopolistic Banking Sector of Mongolia and Polymatrix Games of Three Players
Известия Иркутского государственного университета: Серия "Математика", 2015 A problem of competition between the three largest banks of the Mongolia major crediting sector is investigated. Modeling of the conflict is carried out using the apparatus of three person polymatrix games (hexamatrix games).
