nonoptimal
Less than ideal
Nonoptimal means not the best possible; falling short of ideal.
The term appears frequently in technical and academic contexts where optimization matters: a nonoptimal solution, nonoptimal resource allocation.
It suggests room for improvement without implying failure—something can work adequately while still being nonoptimal.
