Both words can translate to "computational", but which should you choose?

Japanese Option A

けいさんきかがく (keisankikagaku)
C2 / CEFR Syllabus
VS
Japanese Option B

計算複雑度理論

けいさんふくざつどりろん (keisannfukuzatsudoriron)

Nuance Contrast & Translation Difference

When translating "computational" into Japanese, you must choose carefully between 計算幾何学 and 計算複雑度理論. In Japanese, 計算幾何学 (けいさんきかがく (keisankikagaku)) is typically associated with "computational geometry" (Syllabus Level: C2) and represents Essential structural term in CEFR C2 vocabulary syllabus.. On the other hand, 計算複雑度理論 (けいさんふくざつどりろん (keisannfukuzatsudoriron)) maps to "computational complexity theory" (Syllabus Level: C2) and represents Essential structural term in CEFR C2 vocabulary syllabus.. A literal translation of "computational" can often sound unnatural to native Japanese speakers if mixed up!
