Yay, I found the easter egg :D But now I'm stuck :(

what

Do I need to make random tests harder? o_0

Sorry for offtop, but what software you used to generate this image? I was looking for something like that for a while

My solution is just an optimized version of permutating active tasks and calculating minimum time needed, so it's supposed to work.

How does your algorithm fare on this test case?

1. Wash: carrots for 10 minutes
2. Wash: rice for 5 minutes
3. Boil: rice (takes 10 minutes)
4. Boil: carrots (takes 2 minutes)
5. Add: carrots for 20 minutes

The current reference solution returns suboptimal answers in some cases, for example:

1. Wash: meat (takes 2 minutes)
2. Wash: eggs (takes 1 minutes)
3. Peel: eggs (takes 6 minutes)
4. Cut: cheese (takes 2 minutes)
5. Fry: cheese for 13 minutes
6. Grate: cheese (takes 2 minutes)
7. Fry: cheese for 30 minutes
8. Wash: eggs (takes 3 minutes)
9. Wash: eggs (takes 2 minutes)

As shown in the Gantt chart below, the optimal answer is no more than (4) + (5) + (6) + (7) = 47 minutes, while the reference solution returns 48.

Thanks, should be fixed now. I also added a fixed case similar to this to the tests.

The current reference solution returns a clearly incorrect answer in the following test case:

poly1 = [
    (Fraction(-27, 1), Fraction(153, 1)), 
    (Fraction(31, 1), Fraction(70, 1)), 
    (Fraction(156, 1), Fraction(81, 1)), 
    (Fraction(68, 1), Fraction(14, 1)), 
    (Fraction(121, 1), Fraction(-71, 1)), 
    (Fraction(8, 1), Fraction(-29, 1)), 
    (Fraction(-85, 1), Fraction(-93, 1)), 
    (Fraction(-66, 1), Fraction(0, 1)), 
    (Fraction(-176, 1), Fraction(46, 1)), 
    (Fraction(-51, 1), Fraction(61, 1))
]
poly2 = [
    (Fraction(11, 1), Fraction(-47, 1)), 
    (Fraction(-161, 1), Fraction(-100, 1)), 
    (Fraction(-91, 1), Fraction(-4, 1)), 
    (Fraction(-243, 1), Fraction(63, 1)), 
    (Fraction(-42, 1), Fraction(59, 1)), 
    (Fraction(36, 1), Fraction(153, 1)), 
    (Fraction(90, 1), Fraction(54, 1)), 
    (Fraction(290, 1), Fraction(46, 1)), 
    (Fraction(122, 1), Fraction(-11, 1)), 
    (Fraction(168, 1), Fraction(-111, 1))
]

Ahh, that's on me. There was an error in comparing polygons that was corrected in the sample tests but not the main ones. Should be fixed now.

In Fixed Tests - Simple Case - Test 1, I got the following message:

(
    (Fraction(20, 1), Fraction(0, 1)), 
    (Fraction(20, 1), Fraction(11, 1)), 
    (Fraction(30, 1), Fraction(15, 1)), 
    (Fraction(15, 1), Fraction(30, 1)), 
    (Fraction(11, 1), Fraction(20, 1)), 
    (Fraction(0, 1), Fraction(20, 1)), 
    (Fraction(0, 1), Fraction(0, 1))
)
should match
[
    (Fraction(0, 1), Fraction(0, 1)), 
    (Fraction(0, 1), Fraction(20, 1)), 
    (Fraction(11, 1), Fraction(20, 1)), 
    (Fraction(15, 1), Fraction(30, 1)), 
    (Fraction(30, 1), Fraction(15, 1)), 
    (Fraction(20, 1), Fraction(11, 1)), 
    (Fraction(20, 1), Fraction(0, 1))
]

Could you explain why my answer is incorrect? 🤔

Failed to import gmpy2. Raise an issue in the discourse if you think that what you try to import is legit.

Really, I have no chance to optimise Python ( or the math ) enough to ever solve it.

I feel like if you tried to solve the kata you'd understand better (I know you won't).
