What is Surrogate-Assisted Evolutionary Optimization?
Surrogate-Assisted Evolutionary Optimization integrates surrogate models like Kriging with evolutionary algorithms to minimize expensive fitness evaluations in multi-objective black-box optimization problems.
This approach uses Gaussian processes for approximation, focusing on infill sampling, model management, and uncertainty handling to approximate Pareto fronts efficiently. Key works include Pan et al. (2018) with 422 citations on classification-based SAEAs for many-objective problems and foundational studies like Ong et al. (2006) with 511 citations on adaptive memetics. Over 10 listed papers span 2006-2023, emphasizing practical reductions in computational cost.
Why It Matters
Surrogates enable optimization of computationally intensive systems in aerospace design and composite laminates, as shown in Couckuyt et al. (2010) with 138 citations on electromagnetic problems and Arian Nik et al. (2012) with 130 citations on curvilinear fiber composites. Pan et al. (2018) demonstrate effectiveness for expensive many-objective tasks, reducing evaluations while maintaining Pareto accuracy. This supports real-world applications where simulations exceed millions of CPU hours.
Key Research Challenges
Surrogate Model Accuracy
Surrogates like Kriging struggle with high-dimensional or non-smooth landscapes, leading to poor Pareto approximations. Pan et al. (2018) highlight limitations in many-objective settings with few evaluations. Balancing model fidelity and update frequency remains critical.
Infill Sampling Strategies
Selecting optimal points for true evaluations amid uncertainty is challenging in multi-objective spaces. Couckuyt et al. (2010) apply surrogates to electromagnetics but note infill efficiency gaps. Adaptive strategies must quantify trade-offs between exploration and exploitation.
Model Management Overhead
Managing ensembles of surrogates increases computational cost, countering evaluation savings. Ong et al. (2006) discuss adaptive memetics but underscore parameter tuning burdens. Scalability to large populations demands efficient pruning and fusion techniques.
