Active causal structure learning with advice

D Choo, T Gouleakis… - … Conference on Machine …, 2023 - proceedings.mlr.press
We introduce the problem of active causal structure learning with advice. In the typical well-
studied setting, the learning algorithm is given the essential graph for the observational …

A universal error measure for input predictions applied to online graph problems

G Bernardini, A Lindermayr… - Advances in …, 2022 - proceedings.neurips.cc
We introduce a novel measure for quantifying the error in input predictions. The error is
based on a minimum-cost hyperedge cover in a suitably defined hypergraph and provides a …

[HTML][HTML] A pattern-based algorithm with fuzzy logic bin selector for online bin packing problem

B Lin, J Li, T Cui, H **, R Bai, R Qu… - Expert Systems with …, 2024 - Elsevier
The online bin packing problem is a well-known optimization challenge that finds application
in a wide range of real-world scenarios. In the paper, we propose a novel algorithm called …

Learning-augmented online TSP on rings, trees, flowers and (almost) everywhere else

E Bampis, B Escoffier, T Gouleakis, N Hahn… - arxiv preprint arxiv …, 2023 - arxiv.org
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 …

Online bipartite matching with imperfect advice

D Choo, T Gouleakis, CK Ling… - arxiv preprint arxiv …, 2024 - arxiv.org
We study the problem of online unweighted bipartite matching with $ n $ offline vertices and
$ n $ online vertices where one wishes to be competitive against the optimal offline …

Learning multivariate Gaussians with imperfect advice

A Bhattacharyya, D Choo, PG John… - arxiv preprint arxiv …, 2024 - arxiv.org
We revisit the problem of distribution learning within the framework of learning-augmented
algorithms. In this setting, we explore the scenario where a probability distribution is …

Online time-windows TSP with predictions

S Chawla, D Christou - arxiv preprint arxiv:2304.01958, 2023 - arxiv.org
In the Time-Windows TSP (TW-TSP) we are given requests at different locations on a
network; each request is endowed with a reward and an interval of time; the goal is to find a …

Non-Clairvoyant Makespan Minimization Scheduling with Predictions

E Bampis, A Kononov, G Lucarelli… - … on Algorithms and …, 2023 - drops.dagstuhl.de
We revisit the classical non-clairvoyant problem of scheduling a set of n jobs on a set of m
parallel identical machines where the processing time of a job is not known until the job …

Online TSP with known locations

E Bampis, B Escoffier, N Hahn, M Xefteris - Algorithms and Data Structures …, 2023 - Springer
In this paper, we consider the Online Traveling Salesperson Problem (OLTSP) where the
locations of the requests are known in advance, but not their arrival times. We study both the …
