One of the main difficulties of applying an evolutionary algorithm (or, as a matter of fact, any heuristic method) to a given problem is to decide on an appropriate set of parameter values. Typically these are
摘要: Discusses methods proposed for handling nonlinear programming constraints by evolutionary algorithms for numerical optimization problems. Difficulties connected with solving general nonlinear programming problem; Approaches that have emerged in the evolutionary computation community....
Dynamic Parameter Control in Simple Evolutionary Algorithms 5 CONCLUSIONS We studied two variants of the (1 + 1) EA with dynamic parameter control. The first variant used a probabilistic selection mechanism that accepted deteriorations with a probability depending on a parameter α. We proved on a...
2.3 Multi-objective optimization and evolutionary algorithms In traditional optimization, the goal is to find a single optimal solution that maximizes or minimizes a specific objective function. In many real-world scenarios, decision-makers face situations where there are multiple, often conflicting, obje...
Differential evolution (DE), proposed by Storn and Price [1], [2] in 1995, has become a hotspot in the community of evolutionary computation. Similar to other evolutionary algorithms (EAs), DE is a population-based optimization algorithm. In DE, each individual in the population is called a...
Inference of sequence homology is inherently an evolutionary question, dependent upon evolutionary divergence. However, the insertion and deletion penalties in the most widely used methods for inferring homology by sequence alignment, including BLAST and profile hidden Markov models (profile HMMs), are no...

algorithms8,9,10and evolutionary algorithms (EAs) such as the shuffled complex evolution method (SCE-UA)11have been introduced for calibration. For example, nearly all models for the rainfall-runoff process12,13and for ecosystem dynamics14involve unobservable parameters that require calibration. More...
We consider grid search (GS) as a representative of manual tuning and particle swarm optimization (PSO) as a representative of evolutionary algorithms. Fig. 9(e)-(h) demonstrate the optimization of DCNN models using these different methods. Despite varying approaches to hyperparameter optimization,...
The improved algorithm is applied to machine learning parameter optimization, which can enhance the accuracy of machine learning model in classification prediction tasks. In particular, the prediction accuracy of acute appendicitis is effectively improved by combining machine learning algorithms and meta-heur...
