Noodle Shop

Due Monday, August 10th, before midnight Pacific Time.

Note: You can work on this assignment with a partner if you want to. If you do, the two of you should make one submission on Gradescope with both of your names listed. You'll need to do this every time you submit.

Backstory

If there's one thing this town lacks it's quality noodles. So you quit your job as a programmer and set out to fix that. You buy a whole bunch of pots, you rent a stall at a nearby farmers' market, and you hang out your sign:

Fresh Hot Noodles
(in fifteen minutes or they're free)

Now all you have to do is cook some noodles and wait for customers! And figure out how to pay that rent...

Your Assignment

• Write a class that simulates running a noodle shop.
• Make at least enough money to pay for your rent and ingredients.
• You must serve all the customers whose orders you accept.
• You can use anything from the standard library.
• Make sure you don't print anything that isn't explicitly allowed.
• Make sure you don't have any memory leaks.

Your Day

Your day starts at eight in the morning, and is divided into minutes. You accept orders until eight in the evening, and you keep your kitchen open until eight thirty to handle any orders that came in right before eight.

Every minute, the framework code will call two functions on your shop:

• First it will call orders(minute, orderlist) to let you know about any new orders coming in. Return a list of all the orders you choose to accept. If you want to reject an order you must do it here: there's no way to cancel an order that you previously accepted.

• Then it will call action(minute) to ask what you want in that minute. Return a new Action describing what you choose to do. Your available actions are described in the Making Noodles section, below.

The orders() function will be still called between eight and eight thirty PM, but there will never be any new orders during this time.

Making Noodles

To make noodles, all you need is a pot and ingredients! You have the ingredients to make any number of meals, but you have a limited number of pots. In order to make money, you'll need to manage your pots carefully; the actions you can take all relate to your pots. All actions take one minute.

• Take the cook action to start a batch of noodles in a clean pot.

  • This action will generate batch_size servings of noodles.
  • The noodles will be ready to serve in cook_time minutes.
  • The noodles will go stale half an hour after they're ready.
  • The pot you use is now dirty.

• Take the serve action to take noodles out of pots and give them to your customers (this is how you get paid!). You can serve any number of customers with a single serve action.

• Take the clean action to clean a pot. If there are any noodles still in the pot, they will be discarded. All your pots are initially clean.

• If you don't want to do any of these things, you can take no action.

Making Money

You rent your stall by the day. The amount you pay for the current day is passed to the create function. You'll want to make as much money as possible regardless of how much you paid, but you'll have the number for reference.

You have all your ingredients already, but for accounting purposes you only pay for your ingredients when you use them. You'll pay a noodle's ingredient_cost when you start cooking a new batch of that noodle.

Customers pay you the noodle's serving_price when they get their noodles. If they don't have to wait very long they'll give you a tip:

• Customers who get their noodles the same minute they order them will give you a one dollar (100 cent) tip.
• The tip decreases by ten cents per minute until it reaches zero. Customers who wait ten to fifteen minutes will pay for their noodles, but won't tip.
• Customers who wait more than fifteen minutes get their noodles free.

Invalid Actions

There are some things you will never do, because you have standards:

• You will never use more pots than you have.
• You will never cook noodles in a dirty pot.
• You will never serve anyone stale noodles.
• You will never serve anyone undercooked noodles.
• You will never serve anyone the wrong type of noodle.
• You will never fulfill orders for the same type of noodle out of order.
• You will never fail to fulfill an order you accepted.
• You will never fulfill an order more than once.

Extra Credit

To get full credit, don't perform any invalid actions, fulfill all the orders you accept, and make enough money to pay for your rent and any ingredients you use. To get extra credit, make as much money as you can! The best submission will get 10 extra points, the next best will get 9, and so on.
