Can you catch a fugitive moving between seven planets in ten moves?

Can you solve the seven planets riddle? - Edwin F. Meyer · 6:01 · Video: TED-Ed · Watch at the source

In short: This video presents a logic puzzle where you must apprehend criminals hiding on one of seven planets. Because the fugitives can move to a different planet after each search, you must find a specific sequence to guarantee their capture within ten warps.

Edwin F. Meyer explores a mathematical strategy for an interstellar pursuit. The core challenge lies in the fact that the criminals are mobile; every time you search one location, they can relocate to any of the other six planets. To succeed, you cannot simply guess, but must devise a sequence that systematically narrows down their possible locations until they have nowhere left to hide.

The video demonstrates how to solve this specific riddle by identifying a guaranteed path to capture the fugitives in ten warps or less. It serves as an introduction to the logic of search patterns and the constraints of moving targets.
