Introduction

The growing complexity of medical data necessitates advanced computational techniques, with evolutionary algorithms emerging as key players in fields like feature selection for medical data classification. These intelligent algorithms excel at pinpointing the most relevant features from vast, intricate datasets, a capability fundamental to enhancing diagnostic accuracy and crafting more effective treatment strategies in healthcare [1].

Beyond specific tasks, a broader perspective reveals how nature-inspired algorithms, including the family of evolutionary algorithms, find diverse applications across numerous healthcare domains. This comprehensive overview highlights their utility in addressing complex challenges, from medical diagnosis and prognosis to facilitating drug discovery and advancing personalized medicine, showcasing their transformative potential for healthcare innovation [2].

Looking across the medical landscape, evolutionary computation techniques are widely applied to a spectrum of medical challenges. This broad approach encompasses everything from optimizing intricate treatment plans to significantly improving diagnostic precision. This work provides a succinct summary of the current landscape and promising future of harnessing computational evolution for profound medical advancements [3].

A critical area benefiting from these techniques is computational drug discovery and design. Evolutionary algorithms act as powerful optimization tools, enabling researchers to efficiently explore vast chemical spaces, accurately predict molecular properties, and refine drug candidates. This process significantly accelerates the journey of new therapeutics from concept to market, though it also involves navigating both notable successes and persistent challenges [4].

In medical image analysis, evolutionary computing methods offer a comprehensive suite of solutions. They dissect complex visual data through techniques for segmentation, classification, and registration of medical images. Such applications enhance the accuracy and automation of image processing, which is indispensable for clinical diagnosis and ongoing research, thereby underscoring the vital role of these algorithms in deciphering complex visual medical information [5].

The concept of hybrid evolutionary algorithms further amplifies problem-solving capabilities, particularly in biomedical engineering where complex optimization problems are common. By strategically combining evolutionary techniques with other search or optimization methods, these hybrid approaches yield more robust and efficient solutions. This includes applications in medical device design, sophisticated treatment planning, and intricate data analysis, truly demonstrating the profound power of synergy in computational intelligence [6].

Bioinformatics presents another domain where evolutionary algorithms play a pivotal and significant role. They are adept at tackling various computational problems inherent in biological data, such as gene prediction, protein structure prediction, sequence alignment, and the construction of phylogenetic trees. These tools empower researchers to decipher complex biological information, propelling forward our understanding of life sciences [7].

The integration of evolutionary algorithms with deep learning models represents a forward-thinking approach to medical applications. Here, EAs are strategically employed to optimize critical aspects of deep learning, from hyperparameter tuning to neural architecture search. This optimization leads directly to enhanced performance in medical image analysis, more accurate disease diagnosis, and personalized treatment recommendations, ultimately fostering more reliable and precise Artificial Intelligence in healthcare [8].

For direct patient impact, evolutionary algorithms are making significant strides in disease diagnosis and prognosis. These adaptive optimization techniques skillfully analyze complex medical data, discern subtle patterns, and construct highly predictive models. These models, in turn, provide clinicians with invaluable aid for early detection and forecasting disease progression, offering compelling insight into avenues for improving patient outcomes [9].

Lastly, a specialized application involves multiobjective evolutionary algorithms (MOEAs) specifically tailored for feature selection in medical diagnosis. MOEAs are adept at simultaneously optimizing multiple, often inherently conflicting, objectives—such as maximizing diagnostic accuracy while minimizing the number of features used. This powerful capability allows for the identification of optimal feature subsets, thereby unequivocally demonstrating the practical value of MOEAs in enhancing both the precision and interpretability of diagnostic models [10].

Evolutionary algorithms (EAs) represent a powerful class of computational techniques, inspired by natural selection, finding widespread application across various healthcare domains. They are especially adept at tackling complex optimization problems that are pervasive in medicine and biomedical engineering. A systematic review highlights their effectiveness for feature selection in medical data classification, where they identify the most relevant features from high-dimensional datasets. This capability is critical for enhancing diagnostic accuracy and developing more effective treatment strategies [1]. The broader utility of nature-inspired algorithms, including EAs, in healthcare spans from diagnosis and prognosis to drug discovery and personalized medicine, showcasing their potential to innovate healthcare solutions extensively [2].

Evolutionary computation techniques offer a comprehensive approach to a wide array of medical challenges, ranging from optimizing treatment plans to improving diagnostic precision [3]. When it comes to disease diagnosis and prognosis, these adaptive optimization techniques skillfully analyze complex medical data to identify patterns and construct predictive models. This helps clinicians achieve earlier detection and more accurate forecasting of disease progression, leading to improved patient outcomes [9].

In particular, for medical image analysis, evolutionary computing methods provide robust solutions for tasks such as segmentation, classification, and registration of medical images. These applications significantly improve the accuracy and automation of image processing, which is crucial for both clinical diagnosis and research [5]. Furthermore, specialized approaches like multiobjective evolutionary algorithms (MOEAs) are particularly useful for feature selection in medical diagnosis. MOEAs allow for the simultaneous optimization of conflicting objectives such as maximizing accuracy while minimizing the number of features, enhancing the precision and interpretability of diagnostic models [10].

Beyond diagnostics, evolutionary algorithms are instrumental in modern computational drug discovery and design. They facilitate the exploration of vast chemical spaces, the prediction of molecular properties, and the optimization of drug candidates, thereby accelerating the development of new therapeutics [4]. In bioinformatics, EAs play a significant role in deciphering complex biological information. Their applications include gene prediction, protein structure prediction, sequence alignment, and phylogenetic tree reconstruction, advancing our understanding of life sciences [7]. The challenges within biomedical engineering also benefit from hybrid evolutionary algorithms, which combine evolutionary techniques with other optimization methods. This leads to more robust and efficient solutions for problems like medical device design, treatment planning, and advanced data analysis [6].

A forward-looking application involves the integration of evolutionary algorithms with deep learning models for various medical applications. EAs are employed to optimize deep learning aspects, such as hyperparameter tuning and neural architecture search. This synergy results in enhanced performance in medical image analysis, disease diagnosis, and treatment recommendations, contributing to more accurate and reliable Artificial Intelligence in healthcare [8]. The ongoing research and development in these areas continuously highlight the critical role of evolutionary algorithms in processing complex medical and biological data, transforming raw information into actionable insights for healthcare professionals and researchers. These methods hold substantial promise for future innovations, pushing the boundaries of what is possible in medical science and patient care.
