Engineering Contradiction Analysis
1Adaptability or versatility
If traditional genetic algorithms are used for optimization, then solution generation can proceed, but hyperparameter optimization is difficult and adaptation to complex problem spaces is limited
Solution Approach 1:
The patent introduces a neural network as an intermediary component between the genetic algorithm and the hyperparameter selection process. The neural network learns optimal hyperparameter values based on problem characteristics and genetic algorithm performance, mediating the complex interaction between problem space and algorithm parameters. This resolves the contradiction by automating hyperparameter optimization through the neural network mediator, improving adaptability without manually increasing system complexity.
Solution Approach 2:
The patent dynamically changes hyperparameter values based on problem characteristics and genetic algorithm performance metrics. The neural network continuously adjusts hyperparameters such as population size, mutation rate, and crossover rate according to the observed problem complexity and solution progress. This dynamic parameter adaptation enables the system to handle complex problem spaces effectively while maintaining automated optimization.
2Productivity
If reinforcement learning is integrated with genetic algorithm, then hyperparameter optimization improves, but system complexity increases
Solution Approach 1:
The patent merges reinforcement learning with the genetic algorithm into a unified hybrid system. The neural network agent and genetic algorithm work together as an integrated optimization framework, where the neural network selects hyperparameters and the genetic algorithm generates solutions. This merging improves productivity by combining the strengths of both approaches while managing complexity through unified system architecture.
Solution Approach 2:
The hybrid system implements self-service through automated hyperparameter optimization. The neural network agent autonomously monitors genetic algorithm performance and adjusts hyperparameters without external intervention. This self-service capability improves solution generation efficiency by eliminating manual tuning while the system manages its own complexity through autonomous operation.
3Manufacturing precision
If manual hyperparameter tuning is used, then system simplicity is maintained, but optimization performance is limited
Solution Approach 1:
The patent performs preliminary action by having the neural network pre-learn optimal hyperparameter strategies before executing the genetic algorithm. The neural network is trained on problem characteristics and historical performance data to predict optimal hyperparameter values in advance. This preliminary preparation improves optimization precision while reducing the time lost during actual hyperparameter tuning, as the system starts with pre-determined optimal parameters.
Solution Approach 2:
The patent implements continuous feedback between the genetic algorithm performance and neural network hyperparameter selection. The neural network receives feedback on solution quality and genetic algorithm progress, then adjusts hyperparameters accordingly. This feedback loop improves optimization precision by adapting to actual performance while automating the tuning process, eliminating the time loss associated with manual trial-and-error tuning.
