When indemnity insurance fails: Parametric coverage under binding budget and risk constraints
Journal of Risk and Insurance, EarlyView.Abstract In high‐risk environments, traditional indemnity insurance is often unaffordable or ineffective, despite its well‐known optimality under expected utility. We compare excess‐of‐loss indemnity insurance with parametric insurance within a common mean‐variance framework, allowing for fixed costs, heterogeneous premium loadings, and binding budget ...

Solving Flexible Job-Shop Scheduling Problems Based on Quantum Computing
EntropyFlexible job-shop scheduling problems (FJSPs) represent one of the most complex combinatorial optimization challenges. Modern production systems and control processes demand rapid decision-making in scheduling.

Penalized Convex Estimation in Dynamic Location Models
Journal of Time Series Analysis, EarlyView.ABSTRACT This paper studies L1$$ {L}^1 $$‐penalized estimation for location models yt=mt+ϵt$$ {y}_t={m}_t+{\epsilon}_t $$, where mt$$ {m}_t $$ is defined by a possibly non‐Markovian recursion and ϵt$$ {\epsilon}_t $$ is a martingale difference sequence with possibly time‐varying conditional variance.

Reinforcement Learning for Jump‐Diffusions, With Financial Applications
Mathematical Finance, EarlyView.ABSTRACT We study continuous‐time reinforcement learning (RL) for stochastic control in which system dynamics are governed by jump‐diffusion processes. We formulate an entropy‐regularized exploratory control problem with stochastic policies to capture the exploration–exploitation balance essential for RL.

Second-order mollified derivatives and optimization [PDF]
The class of strongly semicontinuous functions is considered. For these functions the notion of mollified derivatives, introduced by Ermoliev, Norkin and Wets, is extended to the second order.

A polynomial-time recursive algorithm for some unconstrained quadratic optimization problems
, 2011 Determining the cells of an arrangement of hyperplanes is a classical problem in combinatorial geometry. In this paper we present an efficient recursive procedure to solve it.In fact, by considering a connection between the latter problem and optimality ...

A Threshold‐Price Approach to Oligopolistic Competition: A Resolution to the Bertrand Paradox
The Manchester School, EarlyView.ABSTRACT In homogeneous‐product markets, changing a price does more than alter a firm's profit margin: it may also determine which competitors can profitably remain active. This paper develops a new static theory of price competition based on this observation.

The African Mole‐Rat Genus Cryptomys and Its Species: Distinct in Their Genes and Habitats
Zoologica Scripta, EarlyView.ABSTRACTThe African mole‐rat genus Cryptomys comprises five morphologically cryptic lineages distributed across South Africa and in Zimbabwe, historically treated as subspecies of C. hottentotus (C. h. hottentotus, C. h. mahali, C. h. natalensis, C. h. pretoriae and C. h. nimrodi).

Simultaneous Optimization of Design Layout and Material Properties in Reinforced Concrete Structures
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT The sustainable transformation of the building sector requires the design of mechanically efficient civil engineering structures, the consideration of material properties in the design layout plays an important role in this context. Steel‐reinforced concrete is an anisotropic bi‐material composite, which represents one of the most popular ...
