Exact Solutions for the Moving Firefighter Problem on Trees

Networks, Volume 88, Issue 1, Page 42-58, July 2026.
ABSTRACT The moving firefighter problem (MFP) is a more realistic variant of the classic firefighter problem (FP), where firefighters require time for both travel and defense. Unfortunately, the only known exact solution for the MFP does not scale. In this paper, we establish that the MFP is NP‐complete on trees of maximum degree three and present four

Geometric Planted Matchings Beyond the Gaussian Model

Random Structures &Algorithms, Volume 68, Issue 4, July 2026.
ABSTRACT We consider the problem of recovering an unknown matching between a set of n$$ n $$ randomly placed points in ℝd$$ {\mathbb{R}}^d $$ and random perturbations of these points. This can be seen as a model for particle tracking and more generally, entity resolution.

Leveraging the Highly Data‐Rich Northeast Arctic Cod (Gadus morhua, Gadidae) to Identify Key Biophysical Factors Behind Recruitment Success

Fish and Fisheries, Volume 27, Issue 4, Page 1006-1027, July 2026.
The recent markedly reduced recruitment success (recruitment per spawner stock biomass) of Northeast Arctic cod (Gadus morhua, Gadidae) is seemingly largely attributed to the joint negative effect of increased temperature and cannibalism but also predation on the postlarvae by Northeast Atlantic mackerel (Scomber scombrus, Scombridae).

Do robots boost productivity? A quantitative meta‐study

Journal of Economic Surveys, Volume 40, Issue 3, Page 1531-1571, July 2026.
ABSTRACT This meta‐study analyzes the productivity effects of industrial robots. More than 1800 estimates from 85 primary studies are collected. The meta‐analytic evidence suggests that robotization has so far provided, at best, a small boost to productivity. There is strong evidence of publication bias in the positive direction.

Markov Determinantal Point Process for Dynamic Random Sets

Journal of Time Series Analysis, Volume 47, Issue 4, Page 784-802, July 2026.
ABSTRACT The Law of Determinantal Point Process (LDPP) is a flexible parametric family of distributions over random sets defined on a finite state space, or equivalently over multivariate binary variables. The aim of this paper is to introduce Markov processes of random sets within the LDPP framework. We show that, when the pairwise distribution of two

Automated Bandwidth Selection for Inference in Linear Models With Time‐Varying Coefficients

Journal of Time Series Analysis, Volume 47, Issue 4, Page 854-875, July 2026.
ABSTRACT The problem of selecting the smoothing parameter, or bandwidth, for kernel‐based estimators of time‐varying coefficients in linear models with possibly endogenous explanatory variables is considered. We examine automated bandwidth selection by means of cross‐validation, a nonparametric variant of Akaike's information criterion, and bootstrap ...
