SPACECATS!

Explore the universe of optimal cattednes.

Your mission

You are an intrepid engineer, founding fresh feline frontiers in new galaxies, such that they may be populated, as ours is, with adorable kittens. Of course, the attributes of any one galaxy strongly affect the ability for a cat to survive there. Luckily for you, modern data transfer and cloning techniques allow you to spawn a particular cat in a particular galaxy and get a report back of how well it fared.

Using these amazing technologies, you are to report back on the optimal cat you can produce in each galaxy. Delivery your report to [email protected], including the cats you discovered, the code you wrote, and a description of your process.

Happy cat catching!

API

The API currently lives at http://spacecats.heroku.com

List galaxies

GET /galaxies responds with a comma-separated list of known galaxies

Example

GET /galaxies
=> milky_way,andromeda

Fitness

GET /galaxies/<galaxy> is a fitness function that expects three parameters:

• weight: The weight of your Spacecat, between 1 and 1000 kg
• limbs: The number of limbs your Spacecat has, between 0 and 100
• color: A hex RGB string indicating the color of your Spacecat
• batch: (optional) true if you're submitting a batch of attributes

It responds with an integer indicating how well your Spacecat survived the galaxy. Obviously, higher values are better.

Batching

By including batch=true in your request, you can submit batches of Spacecat attributes to be evaluated all at once. The response becomes a comma-separated list of all fitnesses.

Examples

• A standard black cat:

  GET /galaxies/milky_way?weight=3&limbs=4&color=333333
  => 1

• A fictitious, yellow megacat:

  GET /galaxies/milky_way?weight=300&limbs=60&color=FFFF00
  => 0

• Both in a batch:

  GET /galaxies/milky_way?batch=true&weight=3,300&limbs=4,60&color=333333,FFFF00
  => 1,0
