TED-Ed: A riddle of ice and fire dragons | Henri Picciotto

The video tutorial addresses the challenge of assigning territories to Elder Dragons, ensuring they don't border dragons of the same type to prevent conflicts. Initially, the focus is on creating new regions for fire and ice dragons using a map coloring strategy. The tutorial then shifts to a new scenario with additional dragon types, requiring advanced techniques to manage territories. The solution involves systematic map coloring and strategic region division to accommodate all dragons without conflict.

What is the main challenge when assigning regions to Elder Dragons?

• Making sure all dragons are on the East Coast

• Preventing dragons of the same type from bordering each other

• Assigning regions based on dragon size

• Ensuring each dragon has a unique type of region

Why is it important to have an even number of regions meeting at a point?

• To prevent dragons from flying over the ocean

• To allow regions to be colored with two colors

• To ensure dragons can share regions

• To make regions larger

What happens if four regions all border each other?

• They automatically become one large region

• They cannot be colored with three colors

• They must be assigned to the same dragon type

• They can be colored with any number of colors

What is a key strategy for managing territories with three dragon types?

• Allowing dragons to choose their own regions

• Assigning regions randomly

• Breaking up problematic areas by drawing lines

• Using only two colors for all regions

How should you approach coloring the map to fit all dragons?

• Start in one area and radiate out systematically

• Color all regions the same color

• Assign colors based on dragon size

• Begin with the largest region and work inward
