Purpose of the Study:
- To develop an improved genetic algorithm (IGA) for S-system gene network modeling.
- To model the cell cycle control in Xenopus frog egg.
- To identify key genes like cyclin-Cdc2 and Cdc25 involved in MPF activity.
Main Methods:
- Utilizing time-course training datasets based on the Michaelis-Menten model.
- Implementing an improved genetic algorithm with migration and elitism for global search.
- Applying S-system formalism to describe gene activation and inhibition.
Main Results:
