From Estimates to Schedules: Learning-Augmented Restricted Assignment

Michalis Xefteris

In this work, we study Restricted Assignment scheduling on multiple machines, where each job can be processed only on a specified subset of machines and the objective is to minimiz…

Polynomial Time Learning-Augmented Algorithms for NP-hard Permutation Problems

Evripidis Bampis, Bruno Escoffier, Dimitris Fotakis +2

We consider a learning-augmented framework for NP-hard permutation problems. The algorithm has access to predictions telling, given a pair of elements, whether is before…

Improved FPT Approximation for Non-metric TSP

Evripidis Bampis, Bruno Escoffier, Michalis Xefteris

In the Traveling Salesperson Problem (TSP) we are given a list of locations and the distances between each pair of them. The goal is to find the shortest possible tour that visits…

Parsimonious Learning-Augmented Approximations for Dense Instances of -hard Problems

Evripidis Bampis, Bruno Escoffier, Michalis Xefteris

The classical work of (Arora et al., 1999) provides a scheme that gives, for any , a polynomial time approximation algorithm for dense instances of a family of $\mathcal…

Learning-Augmented Online TSP on Rings, Trees, Flowers and (almost) Everywhere Else

Evripidis Bampis, Bruno Escoffier, Themis Gouleakis +4

We study the Online Traveling Salesperson Problem (OLTSP) with predictions. In OLTSP, a sequence of initially unknown requests arrive over time at points (locations) of a metric sp…

The Covering Canadian Traveller Problem Revisited

Niklas Hahn, Michalis Xefteris

In this paper, we consider the -Covering Canadian Traveller Problem (-CCTP), which can be seen as a variant of the Travelling Salesperson Problem. The goal of -CCTP is fin…
