What does nonoptimal mean?
Nonoptimal is a formal adjective meaning that something is not the best possible option, result, or configuration. It is especially common in mathematics, computing, engineering, and scientific analysis, where an outcome can be compared with an optimum value or a system can be evaluated for efficiency. For example, a program may reject a nonoptimal solution and search for a more efficient one, while an experiment may be repeated because its conditions were nonoptimal. The word is more specific than “bad” because it does not necessarily imply complete failure; it means that a better alternative is possible. Nonoptimal is also closely related to “suboptimal,” though “suboptimal” may be somewhat more familiar in general discussion. In everyday speech, people usually say that something is “not optimal” rather than using the adjective directly.
adjectiveNot optimal; not achieving the best possible result or configuration.
- Not optimal; failing to produce the best possible result, value, or configuration.
"The researchers adjusted the parameters until every nonoptimal result was eliminated."
"The software discarded a nonoptimal route and recalculated the journey."
"Her analysis identified several nonoptimal conditions in the experiment."
Nonoptimal turns the familiar idea of “best” into a mathematical diagnosis: if something can improve, it is not yet optimal.

Where does nonoptimal come from?
Nonoptimal was formed by combining the prefix non- with optimal. Optimal comes ultimately from Latin optimus, meaning “best,” while optimum is a related noun denoting the best or most favourable condition. The same Latin root also underlies words such as optimize, optimist, and optimistic.

How nonoptimal is actually used
Chiefly used in technical, scientific, mathematical, and computing contexts. It is more formal than “not the best” and often emphasizes the possibility of measurable improvement.
Easily confused with nonoptimal
Optimal means the best possible, whereas nonoptimal means anything less than the best possible.
