TED-Ed: Can you solve the rogue AI riddle? - Dan Finkel

The video tutorial explains a strategic game where you must shut down an AI named NIM by controlling water levels in a lab. You and NIM take turns lowering the water by 1, 3, or 4 stories, aiming to reach exactly zero. The key to winning is to leave NIM on losing levels, which are multiples of 7 or two more than multiples of 7. By starting at level 25 and lowering the water by 4 stories, you can ensure NIM always faces a losing level, allowing you to win and shut down the AI.

What is the main objective in the mission against NIM?

• To escape from the lab without being noticed

• To disable the AI by hacking its system

• To lower the water level to 0 before NIM

• To increase the water level to 25 stories

What is the significance of a 'losing' level in the game?

• It is a level that resets the game

• It is a level that allows skipping a turn

• It is a level where the player has no winning moves

• It is a level where the player can win immediately

Which levels are considered 'winning' levels?

• Levels that are multiples of 5

• Levels that are multiples of 3

• Levels that are 1, 3, or 4 above a losing level

• Levels that are even numbers

What pattern helps identify losing levels?

• They are prime numbers

• They are always odd numbers

• They are multiples of 5 and three greater than multiples of 5

• They are multiples of 7 and two greater than multiples of 7

What is the first move you should make from level 25 to ensure victory?

• Lower the water level by 3 stories

• Lower the water level by 4 stories

• Lower the water level by 2 stories

• Lower the water level by 1 story
