Translation guide
The English word 'algorithm' is widely used in Japanese as a loanword. For technical contexts, アルゴリズム is the standard term. In more formal or mathematical writing, 算法 may appear, but it is less common. This guide focuses on how to express the concept naturally in Japanese.

In modern Japanese, アルゴリズム is the default choice for 'algorithm' in computing, data science, and everyday tech contexts. 算法 is more formal and may appear in mathematical proofs or historical texts. For most learners, アルゴリズム is sufficient.
