However, MQTT-enabled networks are vulnerable to various security threats, including eavesdropping, weak authentication, and malicious payload injections. Detecting such intrusions is particularly challenging in IoT environments because of constrained resources, high traffic volumes, and heterogeneous attack vectors. To address these challenges, this study proposes an ensemble learning-based Intrusion Detection System (IDS) specifically designed for MQTT-enabled IoT networks. The ensemble integrates Gaussian Naive Bayes (GNB), Kernel-based Support Vector Machines (K-SVM), and Multi-Layer Perceptrons (MLP) as base classifiers, with Logistic Regression serving as the meta-classifier. Among these, MLP plays a pivotal role by leveraging its deep learning capabilities and parallel processing strengths to capture complex, nonlinear attack patterns that are often missed by conventional models. The combination of diverse classifiers in a stacked architecture significantly enhances the system’s precision, scalability, and adaptability. Experimental evaluation of binary and multi-class classification tasks using the MQTT-IoT-IDS2020 dataset demonstrate that the proposed model achieves outstanding detection accuracies of 99.80% and 99.59%, respectively, outperforming traditional machine learning and standalone deep learning approaches. These results highlighted the effectiveness of the ensemble framework, particularly the critical contribution of MLP, in building a robust, high-performance, and scalable intrusion detection solution for secure IoT communications.</p></div>","PeriodicalId":7971,"journal":{"name":"Annals of Mathematics and Artificial Intelligence","volume":"94 3","pages":"395 - 417"},"PeriodicalIF":1.6,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148613088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mutations and recombinations that reduce the distance to an optimum are considered as beneficial. Geometric and combinatorial analysis is used to derive closed-form expressions for transition probabilities between spheres around an optimum giving a complete description of Markov evolution of distances from an optimum over multiple generations. This paves the way for optimization of parameters of mutation and recombination operators. Here we derive optimality conditions for mutation and recombination radii maximizing the probabilities of mutation and crossover into the optimum. The analysis highlights important differences between these evolutionary operators. While mutation can potentially reach any part of the search space, the probability of beneficial mutation decreases with distance to an optimum, and the optimal mutation radius or rate should also decrease resulting in a slow-down of evolution near the optimum. Crossover recombination, on the other hand, acts in a subspace of the search space defined by the current population of strings. However, probabilities of beneficial and deleterious crossover are balanced, and their characteristics, such as variance, are translation invariant in a Hamming space, suggesting that recombination may complement mutation and boost the rate of evolution near the optimum.</p></div>","PeriodicalId":7971,"journal":{"name":"Annals of Mathematics and Artificial Intelligence","volume":"94 1","pages":"127 - 161"},"PeriodicalIF":1.0,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10472-025-09987-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146082839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the LAP occurs as a subproblem in the linear programming (LP) relaxation of the quadratic assignment problem (QAP), we employ our method as a new component in the family of dual-ascent algorithms that provide bounds on the optimal value of the QAP. To make our results applicable to the incomplete QAP, which is of interest in practical use-cases, we also provide a linear-time reduction from the incomplete LAP to the complete LAP along with a mapping that preserves optimality and membership in the relative interior.

We develop postulates ensuring compliance with syntax splitting for inference operators based on a full strict partial order on worlds. By observing that system W satisfies these axioms, it is proven that system W satisfies syntax splitting. We also explore how syntax splitting affects the strict partial order underlying system W and exploit this for answering certain types of queries without having to determine this strict partial order completely.

In the second part of this paper, we lift this limitation and extend system W to also cover inference from belief bases that only satisfy a weaker notion of consistency.
