Condition optimization device, condition optimization method, and program

A condition optimization method, comprising:

• a) obtaining an actual reaction value by observing a predetermined physical property value at a predetermined condition value;
• b) calculating a new condition value by Bayesian optimization;
• c) predicting, by a response surface method, a best physical property value and an optimum condition value at which the best physical property value is obtainable;
• d) determining whether or not convergence has occurred based on the condition value corresponding to the actual reaction value and based on the new condition value;
• and
• e) determining whether or not convergence has occurred based on a difference between the physical property value observed at the optimum condition value and the best physical property value upon occurrence of the convergence being determined in d),
• a), b), c), d), and e) being executed by a computer.

• b) calculating a new condition value by Bayesian optimization;
• c) predicting, by a response surface method, a best physical property value and an optimum condition value at which the best physical property value is obtainable;
• d) determining whether or not convergence has occurred based on the condition value corresponding to the actual reaction value and based on the new condition value;
• and
• e) determining whether or not convergence has occurred based on a difference between the physical property value observed at the optimum condition value and the best physical property value upon occurrence of the convergence being determined in d).
