Rosalind Problems: Fibonacci, Rabbits and Recurrence Relations

[@michaelmoore7568]

this is one of the most information rich tutorial channels that I've ever seen

[@rebelScience]

Thank you so much! Glad you find the content valuable!

[@kroes3236]

I'm enjoying this series so much! I had already done some of the problems but it's very nice to see your explanation and programming.

[@rebelScience]

Thank you so much.

Dear RebelCoder this is my coding to solve Rabbits and Recurrence relations month_total_pair = {1: 1, 2: 1} n = int(input("Please Enter Month! : N = ")) k = int(input("Please Enter litter of rabbit pairs! : k = ")) if n == 1 or n == 2: print(month_total_pair[n]) else: for x in range(3, 41): total_pair = month_total_pair[x-1] + month_total_pair[x-2] * k month_total_pair.update({x: total_pair}) print(month_total_pair[n])

great explanation..keep up the good work..

How do you do a bulk rename at 6:59? edit: Okay I see you do it by right clicking on the word you wish to rename and hitting rename symbol.

[@ВасяИванов-щ6з]

it works for final "children" value count, but matching visualisation and code "parents" looks little bit odd.

[@ВасяИванов-щ6з]

my point is: 1) initial values: children, parents = 1, 0 2) inside for loop: children, parents = parents * offspring, children + parents 3) return (children + parents)

@@ВасяИванов-щ6з ohhh I had a question about this! thank you!

[@lstein8670]

are you taking a break from making video?

[@rebelScience]

Nope. I was working on something else, related to Bioinformatics. Expect new videos very soon.

[@kroes3236]

@@rebelScience nice

[@rusbiology3460]

Do you mind if I translate your videos into Russian and upload them to KZbin?

[@elshroomness]

why did you start with parent = 1, and child = 1, when in the first month there is only 1 child and 0 parents?

[@elshroomness]

apparently there are different ways of counting the resulting bunnies after a given number of months. Below is the code that was mentioned in the video that starts with parent and children starting at 1. def fib_bunnies2(months,offspring): parent,child = 1,1 for itr in range(months - 1): child,parent = parent, parent + (child * offspring) return child fib_bunnies2(5,2) However, this implementation does not reflect the diagram that was show below the code in the video. The code below shows how the code should be written to match the diagram: def fib_bunnies(months, offspring): child, parents = 1, 0 for itr in range(months - 1): child, parents = parents * offspring, child + parents return (child + parents) fib_bunnies(5,2) Notice that inside the for loop there is different ways of incrementing the child and parent variables to result to the same result. credit goes to @Вася Иванов for their comment in this video and helping realize a hidden nuance in recursion. Thanks!
