A Branch-Price-and-Cut algorithm for the Multi-Commodity two-echelon Distribution Problem

EURO Journal on Transportation and Logistics
In the Multi-Commodity two-echelon Distribution Problem (MC2DP), multiple commodities are distributed in a two-echelon distribution system involving suppliers, distribution centres and customers.

Integrability in gravity from Chern-Simons theory

Journal of High Energy Physics
This paper presents a new perspective on integrability in theories of gravity. We show how the stationary, axisymmetric sector of General Relativity can be described by the boundary dynamics of a four-dimensional Chern-Simons theory.

A Branch-and-Price-and-Cut Algorithm for the Inland Container Transportation Problem with Limited Depot Capacity

Applied Sciences
As an effective solution to the first- and last-mile logistics of door-to-door intermodal container transportation, inland container transportation involves transporting containers by truck between terminals, depots, and customers within a local area ...

On-shell functions on the Coulomb branch of $$\mathcal{N}$$ = 4 SYM

Journal of High Energy Physics
We study on-shell functions in the kinematic space for the Coulomb branch of $$\mathcal{N}$$ = 4 SYM. We construct BCFW bridges that help us build bigger on-shell functions.

Using infeasible path cuts to solve Electric Vehicle Routing Problems with realistic charging functions exactly within a branch-and-cut framework

EURO Journal on Transportation and Logistics
The paper investigates the Electric Vehicle Routing Problem with a non-linear concave and strictly monotonic increasing charging function. In the literature, the non-linear charging function is typically approximated by a piecewise linear charging ...

Twists of trigonometric sigma models

Journal of High Energy Physics
We introduce the ℤ N -twisted trigonometric sigma models, a new class of integrable deformations of the principal chiral model. Starting from 4d Chern-Simons theory on a cylinder, the models are constructed by introducing a ℤ N branch cut running along ...
