Enhancing MaxSAT Local Search via a Unified Soft Clause Weighting Scheme
No full textLocal search has been widely applied to solve the well-known (weighted) partial MaxSAT problem, significantly influencing many real-world applications. The main difficulty to overcome when designing a local search algorithm is that it can easily fall into local optima. Clause weighting is a beneficial technique that dynamically adjusts the landscape of search space to help the algorithm escape from local optima. Existing works tend to increase the weights of falsified clauses, and such strategies may result in an unpredictable landscape of search space during the optimization process. Therefore, in this paper, we propose a Unified Soft Clause Weighting Scheme called Unified-SW, which increases the weights of all soft clauses in feasible local optima, whether they are satisfied or not, while preserving the hierarchy among them. We implemented Unified-SW in a new local search solver called USW-LS. Experimental results demonstrate that USW-LS, outperforms the state-of-the-art local search solvers across benchmarks from anytime tracks of recent MaxSAT Evaluations. More promisingly, a hybrid solver combining USW-LS and TT-Open-WBO-Inc won all four categories in the anytime track of MaxSAT Evaluation 2023

Towards More Efficient Local Search for Pseudo-Boolean Optimization
No full textPseudo-Boolean (PB) constraints are highly expressive, and many combinatorial optimization problems can be modeled using pseudo-Boolean optimization (PBO). It is recognized that stochastic local search (SLS) is a powerful paradigm for solving combinatorial optimization problems, but the development of SLS for solving PBO is still in its infancy. In this paper, we develop an effective SLS algorithm for solving PBO, dubbed NuPBO, which introduces a novel scoring function for PB constraints and a new weighting scheme. We conduct experiments on a broad range of six public benchmarks, including three real-world benchmarks, a benchmark from PB competition, an integer linear programming optimization benchmark, and a crafted combinatorial benchmark, to compare NuPBO against five state-of-the-art competitors, including a recently-proposed SLS PBO solver LS-PBO, two complete PB solvers PBO-IHS and RoundingSat, and two mixed integer programming (MIP) solvers Gurobi and SCIP. NuPBO has been exhibited to perform best on these three real-world benchmarks. On the other three benchmarks, NuPBO shows competitive performance compared to state-of-the-art competitors, and it significantly outperforms LS-PBO, indicating that NuPBO greatly advances the state of the art in SLS for solving PBO
The Localization Hypothesis and Machines

Retour d’expérience, CHU de Rouen confronté à une attaque en 2019
No full textInternational audienceIn this article, the author returns to the cyberattack against the Rouen University Hospital dating from 2019. It describes the measures that had to be put in place in order to respond to them and allow the proper functioning of the health system during this period of destabilization. For the author, a cyberattack is managed in six phases: 1. preparation for crisis management; 2. Identification of the cause and extent of the incident; 3. Compartmentalization and implementation of the action plan; 4. Remediation; 5. Restoration; 6. Feedback. For the author, the organization of the crisis unit is specific to each health institution but it is essential to train staff in the risks of a cyberattack.Dans cet article, l’auteur revient sur la cyberattaque à l’encontre du CHU de Rouen datant de 2019. Il décrit les mesures qui ont dû être mises en place afin de répondre à celles-ci et permettre le bon fonctionnement du système de santé durant cette période de déstabilisation. Pour l’auteur, une cyberattaque se gère en six phases : 1. la préparation de la gestion de crise ; 2. Identification de la cause et de l’étendue de l’incident ; 3. Le cloisonnement et la mise en place du plan d’action ; 4. La remédiation ; 5. La restauration ; 6. Le retour d’expérience. Pour l’auteur, l’organisation de la cellule de crise est propre à chaque établissement de santé mais il est indispensable de former le personnel aux risques d’une cyberattaque
On the Changing Political Structure of the Chu State: From an Archaeological Viewpoint
No full textThe emergence of centralised power and polity has long been a crucial problem in historical studies of Eastern Zhou society, and the conclusions of researchers on whether such centralised power was achieved in the state of Chu 楚 have been divided. One reason for this disagreement is due to the differing state of source materials for the Spring and Autumn and Warring States periods, making it difficult to grasp continuity in historical phenomena. In this article, the author re-examines the changing structure of the Chu state based on archaeological evidence from bronze vessels excavated in large quantities in the middle Yangzi River region that enables us to perceive temporal changes throughout the whole Eastern Zhou period. On the basis of archaeological analysis, the author draws three major conclusions. 1) The structure of production and distribution of bronze vessels in the Chu state changed drastically from the late Spring and Autumn period to early Warring States period, and a centralised system emerged by the middle of the Warring States period. 2) In the Spring and Autumn period, the Chu state distributed bronze vessels to the neighbouring polities as a strategy of indirect control in a way similar to that of the Western Zhou dynasty, although this strategy changed to direct domination over the entire middle Yangzi River region. 3) The structure of cemeteries of upper-ranking aristocrats changed through the middle of 5ᵗʰ century BC due to the emerging middle classes, who later became the bureaucrats providing the basis of centralised polity established in the middle Warring States period. Based upon these analyses, the author concludes that the political structure of the Chu state was gradually centralised through 5th century BC, which challenges the traditional views on the centralisation of the Chu polity represented by the drastic and short-term reformation by Wu Qi 吳起. This result calls for reconsideration of the “reformations” (變法) of Eastern Zhou societies from multiple points of view including both historical texts and archaeological materials
