Challenges are publicly discoverable (e.g. through search results) only if both the challenge and its parent project are set to visible. If either is not visible, the challenge will not be discoverable and will not appear in search results.
Visibility only affects discoverability: mappers can still access a challenge directly if they have the public URL to that challenge. This makes it possible to share challenges that are not otherwise discoverable.

Note: virtual projects do not affect visibility of their contained challenges. Only a challenge’s standard parent project is considered when determining discoverability
