Summary: Attraction basins in discrete domains are better understood than those in continuous domains. Research on attraction basins in dynamic problems is scarce. Multi-objective problems are poorly investigated in both domains, with slightly more focus on continuous domains. There is a lack of parallel and scalable algorithms for computing attraction basins, as well as a general framework to unify different definitions/implementations.

Summary: This paper proposes an enhanced chicken swarm optimization algorithm (CSO-EET), which improves the convergence speed and global search ability of the algorithm by balancing the tradeoff between exploration and exploitation. Through comparisons with other improved CSO variants and several state-of-the-art algorithms on both theoretical and practical problems, the experimental results demonstrate that CSO-EET is better than or at least comparable to competitors in most cases.

Summary: The proposed model suggests that firms rely on local search for exploitation and on imitation for exploration. Successful imitation generally occurs at an intermediate level of cognitive proximity, and social and cognitive proximity are substitutes. The model also shows that exploration by imitation is more beneficial in highly complex industries and that small-world networks yield the highest benefits for collective learning.

Summary: One of the major challenges in reinforcement learning is the sparse and delayed rewards in episodic tasks. The existing techniques have difficulties in assigning credits to explored transitions or are misled by behavioral policies, leading to sluggish learning efficiency. To address this, we propose an approach called EMR, which combines intrinsic rewards of exploration mechanisms with reward redistribution to balance exploration and exploitation in such tasks.

Summary: This paper investigates the Floquet stability analysis of equilibrium points and the estimation of pulsating zero velocity curves and Newton-Raphson basins of attraction in the photo-gravitational planar elliptic restricted four body problem under the radiation pressure effect. The study reveals that the stability range of equilibrium points deviates due to radiation pressure and that eccentricity and true anomaly have a considerable impact on the shape and size of forbidden regions.

Summary: This manuscript proposes a novel Opposition-based learning scheme, called PCOBL, to improve the performance of meta-heuristics by maintaining an effective balance between exploration and exploitation. The empirical results demonstrate that PCOBL positively impacts the performance of meta-heuristics, outperforming state-of-the-art algorithms in terms of best-error runs and convergence in most optimization problems. Moreover, the inclusion of PCOBL in the meta-heuristic algorithm has a low impact on its efficiency.

Summary: This paper studies a two parameters family of maps of the plane, which have two different invariant subspaces. The model exhibits two chaotic attractors located in these invariant subspaces, and the parameters at which the attractors exhibit specific characteristics are identified. The occurrence of riddled basin in a global sense is also investigated, and the paper presents a semi-conjugate system and defines a fractal boundary to describe the riddled basin. The model undergoes a sequence of bifurcations, and numerical simulations are provided to validate the findings.

Summary: Previous results suggest that some oscillators have a finite number of Wada basins. However, in this study, we discovered that a nonlinear oscillator can possess a countable infinity of connected Wada basins. The basin cell theorem and generalized basin cell theorem were used to investigate the infinite number of coexisting attractors and their Wada basins. These systematic Wada basins exhibit identical basin structures in each periodic X-axis coordinate interval, resulting in a high level of indeterminacy and extreme sensitivity to initial conditions.

Summary: To evaluate the performance of evolutionary algorithms, they are compared with existing algorithms. However, it is not guaranteed that the experiments are conducted fairly, so it is recommended to repeat the experiments. Challenges may arise if the algorithm's source code is unavailable or needs to be implemented in a different programming language. The differences between programming languages used for algorithm implementation are often overlooked.

Summary: This study investigated the influence of input parameters on the shear strength of RC squat walls and found that ensemble learning models, particularly XGBoost, can effectively predict the shear strength. The axial load had a greater influence than reinforcement ratio, and longitudinal reinforcement had a more significant impact compared to horizontal and vertical reinforcement. The performance of XGBoost model outperforms traditional design models and reducing input features still yields reliable predictions.

Summary: This paper discusses the urgency of learning complex multivariate probability distributions due to the increase in data variability and quantity. It introduces a highly scalable classifier called TAN, which utilizes maximum weighted spanning tree (MWST) for graphical modeling. The paper theoretically proves the feasibility of extending one-dependence MWST to model high-dependence relationships and proposes a heuristic search strategy to improve the fitness of the extended topology to data. Experimental results demonstrate that this algorithm achieves a good bias-variance tradeoff and competitive classification performance compared to other high-dependence or ensemble learning algorithms.
