Background

This technology enables "decision-making" for the selection of preferable things, and can be used for everyday choices to critical decisions in business. Current big data technology makes it possible to statistically analyze past cases and choose options thought to be most effective. However, the information stored in databases is information from the past and thus is not always effective for decisions in the present where unexpected new situations arise. Under these situations, there is a need to go through a process of trial and error efficiently.

Summary

In order to conduct a process of trial and error efficiently, it is important to maintain a balance between focusing on information obtained from past trials and searching for better new options. Through the study of information processing principles used by unicellular organisms, we have discovered that even non-intelligent substances are capable of realizing efficient decision-making as long as they have the property of preserving volume. This method, named the "tug-of-war principle", is found to perform better in terms of efficiency and adaptability than conventional decision-making algorithms.
