Solution Overview
Problem
Existing methods for solving optimization problems and designing electronic devices lack efficiency in generating optimal solutions, particularly in reducing the search space and improving the speed of genetic algorithms.
Innovation Solution
The method involves using a neural network to generate a subset of elements based on their scores, which are then used in a genetic algorithm to produce child elements. The neural network is updated based on the fitness values of these child elements, allowing for adaptive sampling and improved solution derivation.

Engineering Contradiction Analysis
1Productivity
If a neural network is used to generate a subset of elements from a population, then the search space is reduced and processing speed is improved, but the device complexity increases due to the addition of neural network components
Solution Approach 1:
The population is segmented into a subset of high-scoring elements selected by the neural network. This segmentation allows the genetic algorithm to focus computational resources on the most promising candidates rather than processing the entire population, thereby improving solution generation speed while managing system complexity through targeted processing.
Solution Approach 2:
The neural network acts as an intermediary between the population and the genetic algorithm. It pre-processes the population by generating a subset of high-scoring elements, which then serve as input to the genetic algorithm. This intermediary role reduces the search space and improves processing speed while keeping the added complexity localized to the neural network component.
2Loss of time
If the population size is reduced to a subset, then the computational load is decreased, but the solution quality may deteriorate due to limited diversity
Solution Approach 1:
The neural network performs preliminary action by pre-selecting high-scoring elements from the population before the genetic algorithm begins. This preliminary filtering ensures that only the most promising candidates are processed further, reducing computational time while maintaining solution quality through score-based selection criteria that preserve important solution characteristics.
Solution Approach 2:
The system implements feedback mechanisms where the neural network is updated based on the fitness values of child elements generated by the genetic algorithm. This feedback loop allows the neural network to learn from the results and improve its subset selection over time, ensuring that reduced population size does not compromise solution quality while maintaining computational efficiency.
3Productivity
If adaptive sampling is performed based on neural network scores, then the efficiency of the genetic algorithm is improved, but the measurement precision requirements increase for accurate score evaluation
Solution Approach 1:
The system changes parameters by using neural network scores as a new selection criterion for subset generation. These scores serve as a transformed representation of element quality that the genetic algorithm can use for adaptive sampling. The parameter change enables more efficient selection while the neural network's learning capability handles the precision requirements through continuous improvement based on fitness feedback.
