The engineer measured the concavity of the mirror to correct the focusing error.

He pressed the metal sheet concavely to form a shallow basin.

The concaveness of the bowl caused water to pool in the center.

The ancient mirror's concavous surface distorted the reflected images into eerie shapes.

The old carpenter shaped the bowl concavously, following the ancient design.

The sculptor used a special chisel to concavate the wooden panel into a shallow bowl.

The concavers examined the curvature of the metal plates before approving the design.

The concaver inspected each razor blank before giving the blade its precise hollow.

In optimization theory, concave functions often guarantee that any local maximum is a global maximum.

In the algorithm, we assume the objective is a concave function to ensure efficient optimization.
