noun
underdetermined system
Mathematics term for a system of equations with fewer equations than unknowns, leading to infinitely many solutions. Antonym: 優決定系 (overdetermined system).
Antonyms: 優決定系
劣決定系では、解が一意に定まらない。
In an underdetermined system, the solution is not uniquely determined.
この連立方程式は劣決定系なので、パラメータを含む解になる。
Since this system of equations is underdetermined, the solution will involve parameters.
Antonym: an overdetermined system has more equations than unknowns, often with no exact solution.
Compound of 劣 (inferior, here meaning 'under-'), 決定 (determination), and 系 (system). A modern technical term formed from kanji components.
