Inspired by natural selection and genetics, GAs mimic the process of evolution to find optimal solutions to complex engineering problems. In civil engineering, GAs are employed for structural optimization, layout design, and scheduling, among others. By iteratively evolving a population of potential solutions through selection, crossover, and mutation, GAs efficiently explore large solution spaces, identifying high-quality designs that satisfy specified constraints. Their ability to handle nonlinear, multi-objective optimization problems makes GAs a valuable tool for enhancing efficiency and performance in civil engineering projects [2].

Artificial immune system: Artificial Immune Systems (AIS) represent a bio-inspired AI technique increasingly applied in civil engineering for various tasks. Modeled after the human immune system, AIS algorithms use principles of immunology to solve optimization, classification, and anomaly detection problems. In civil engineering, AIS is utilized for structural health monitoring, pattern recognition in geotechnical data, and fault detection in infrastructure systems. By mimicking the adaptive and self-organizing nature of biological immune systems, AIS algorithms can effectively identify and respond to changes and anomalies in civil engineering applications, contributing to enhanced safety, resilience, and performance of infrastructure systems [2].

Combining fuzzy logic with neural networks, RN-FIS models capture the complex relationships and uncertainties inherent in construction projects. In CEM, RN-FIS is utilized for cost estimation, project scheduling, and risk management. By integrating historical project data and expert knowledge, RN-FIS systems adaptively learn and optimize decision-making processes, enhancing project efficiency and performance. Their ability to handle nonlinear relationships and uncertainties makes RN-FIS a valuable tool for addressing the challenges of complexity and variability in construction engineering and management [2,4].

Structural damage detection: The Faster Region-based Convolutional Neural Network (Faster R-CNN) is a cutting-edge AI technique increasingly deployed in civil engineering for structural damage detection. Leveraging deep learning and computer vision, Faster R-CNN models can swiftly and accurately identify damage in civil infrastructure from images or sensor data. In structural engineering, Faster R-CNN aids in detecting cracks, deformations, or structural weaknesses, enabling timely maintenance and enhancing safety. Its high-speed processing and superior detection capabilities make Faster R-CNN a valuable asset in civil engineering for proactive infrastructure monitoring and maintenance, ensuring the resilience and longevity of critical structures [2,4].

As researchers are finding new techniques day by day new technique to called YOLO (You Only Look Once) is founded as option for R-CNN. It is a powerful deep learning technique that can be applied to structural damage detection. YOLO, a deep learning technique, can spot structural damage in images. Trained on labeled photos, YOLO detects and classifies damage types (cracks, spalling) in real-time. While needing good training data and expertise, YOLO's speed and accuracy make it valuable for automated damage detection in infrastructure.

ANNs, inspired by the human brain's neural structure, analyze and interpret large datasets to predict construction costs, material quantities, and project timelines. In QS, ANNs streamline the estimation process, providing more accurate and timely cost projections. By learning from historical data and project specifications, ANNs optimize cost management and budgeting, aiding in decision-making processes for construction projects. Their ability to handle complex relationships and adapt to changing conditions makes ANNs a valuable tool for enhancing efficiency and accuracy in quantity surveying within the civil engineering domain [2,4].

The discussion highlights the significance and applications of various AI techniques in civil engineering. Genetic algorithms offer robust optimization solutions, albeit with potential convergence challenges [2]. Artificial immune systems excel in anomaly detection and risk assessment, while simulated annealing provides versatile optimization capabilities, albeit with slower convergence rates [2]. Synthetic intelligence integrates human expertise with computational models for enhanced decision-making [3]. Genetic programming handles nonlinear problems effectively, though it may require significant computational resources [3]. Swarm intelligence aids in decentralized optimization tasks, albeit with scalability concerns [3]. Hanna-Geotechnical Engineering combines machine learning and geotechnical expertise for soil analysis and slope stability [4]. Responsive Neuro-Fuzzy Inference Systems optimize decision-making in construction engineering [1,4]. Faster Region-based Convolutional Neural Networks excel in structural damage detection [1,4]. Agent-based modeling aids in transportation system analysis and urban planning [2]. Artificial neural networks streamline quantity surveying tasks, albeit with challenges related to data quality and model interpretability [2,4].

Both Genetic Algorithms and Artificial Immune Systems are powerful AI techniques for solving complex optimization problems in civil engineering. Genetic Algorithms is efficient exploration of vast search spaces, good at finding global optima. While Artificial Immune Systems is robustness to noise and adaptable to changing conditions. Genetic Algorithms can get stuck in local optima, requires careful parameter tuning. In other hand Artificial Immune Systems can be computationally expensive, might struggle with highly complex problems.

For instance, could Genetic Algorithms be used for initial exploration, followed by Artificial Immune Systems for fine-tuning solutions in noisy or dynamic environments?

If we discuss Simulated Annealing and Synthetic Intelligence, Simulated Annealing has strengths, efficiently escapes local optima, good for finding near-optimal solutions in complex problems. Also, it handles discrete and continuous variables. While Synthetic Intelligence has strengths, powerful pattern recognition and learning capabilities. It can handle complex non-linear relationships between variables. The weaknesses of Simulated Annealing is, it can be computationally expensive for large problems. It requires careful cooling schedule parameter tuning. And weaknesses of Synthetic Intelligence are, it requires large amounts of training data for good performance. It can be a "black box" - explaining model decisions might be difficult.

Overall, these AI techniques enhance efficiency, performance, and resilience in civil engineering applications, but they require careful consideration of their strengths and limitations for effective implementation [5].

The diverse array of AI techniques discussed in civil engineering, from genetic algorithms to convolutional neural networks, offer innovative solutions for optimization, risk assessment, and infrastructure management.
