It is not paired with a close-neighbour confusable in our dataset, which tends to mean the word is visually distinctive enough to stand on its own.

Etymologically, the entry records: Named after William Rowan Hamilton, Carl Gustav Jacob Jacobi, and Richard E. Bellman.

For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is Hamilton-Jacobi-Bellman equation, spelled H-A-M-I-L-T-O-N---J-A-C-O-B-I---B-E-L-L-M-A-N- -E-Q-U-A-T-I-O-N, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
