            The problem seems to be that you're trying to mutate something that you have not marked as mutable. The add_edge method clearly has to mutate the struct but you have an &self receiver instead of an &mut self. Upon making that change the code compiles:

            Debug memory issue in Haskell
            Asked 2019-Jun-08 at 16:38

            I'm trying to solve the whole Advent of Code series in Haskell.

            I'm encountering a memory issue while solving the 2015/06 exercise where there is a bunch of instructions to turn on, off and toggle lights on a grid. The goal is to count the number of lit lights at the end.

            Given instructions are parsed and stored in a Instruction type, this is the type definition:

            Answered 2019-Jun-08 at 16:38

            I would strongly suggest not using a typeclass. Typeclasses are supposed to have laws, and they should be "rare", in the sense that each type has only a few valid implementations. I would suggest taking initialState and toggle as arguments, but even that is overkill, because the given instructions simply do not make sense with any type that isn't Bool. Just operate on a Matrix Bool directly and you can cut out a good chunk of the code you've written. However, I won't change anything for my answer.

            In any case, I think the issue may be laziness. 1000 * 1000 = 1000000, so each Matrix will be several megabytes in size. On a 64-bit machine, a pointer is 8 bytes, so each Matrix is at least 8 MB, plus a few more for the data behind it. You are mconcating 300 of them (that's what I get from the site) together, but, because you are doing it lazily, all 300 matrices are resident simultaneously, so it's at least 2.4 GB, just for the structures themselves. The cost of filling each of those 300 million pointers with thunks also makes itself known—a thunk is at least one pointer (8 bytes, pointing to code in static memory, making another 2.4 GB), plus its payload, which, here, means more pointers, each one bestowing your computer with another 2.4 GB of memory pressure. I suggest deepseq:

            The task requires to review a sequence of digits and find the sum of all digits that match the next digit in the list. The list is circular, so the digit after the last digit is the first digit in the list. For example:

            1122 produces a sum of 3 (1 + 2) because the first digit 1 matches the second digit and the third digit 2 matches the fourth digit; 1111 produces 4 because each digit (all 1) matches the next; 1234 produces 0 because no digit matches the next; 91212129 produces 9 because the only digit that matches the next one is the last digit, 9

            1. Make sure that you don't use Int due to overflow. Use Integer instead, which can grow arbitrarily large.

            2. As I understand it, the problem asks you to turn on/turn off a rectangular area between opposite corners (a,b), (A,B). I think you interpret the two tuples as rectangle [a..b]x[A..B] but it should be [a..A]x[b..B] (assuming a<=A, b<=B)

            How to avoid Haskell space leak?
            Asked 2018-Jan-03 at 12:36
            Context

            I've started leaning Haskell not long ago by solving this year's Advent of Code tasks.

            While solving Part 2 of Day 17 I've ran into a nasty memory leak (space leak) -- I think.

            (Here's the full README including Part 2, one can only access it after solving Part 1.)

            My solution works and it runs fine, but only with a dirty little hack, which forces Haskell to evaluate an intermediate computation every now and then.

            I'm using traceShow to print the intermediate state to the console after every 5000 iterations (please see here the actual code). This way the program finishes in a reasonable time and doesn't use too much memory.

            The problem: if I remove this (not printing the intermediate state at all, only the last state) the program eats up all available memory. :(

            I've started out with using iterate and then I've read that using that can cause stuff like what I'm noticing. I've replaced it. Nothing. Tried different folds (foldl, foldl', etc.). Nothing. I'm not sure at this point what can cause this although my guess is that at some point there's some not so evident lazy evaluation going on.

            My question: how can I avoid this? What causes this in my case?

            Thank you for your time and insight. Oh, and I'm pretty sure that there are shorter, sweeter solutions to this problem, but currently I'm only interested in what causes the memory leak in my case.

            Testing

            I've isolated the part of the code where I notice this error.

            How to find correct min / max values of a list in Perl 6
            Asked 2017-Dec-05 at 04:26

            New to Perl6, trying to figure out what I'm doing wrong here. The problem is a simple checksum that takes the difference of the max and min values for each row in the csv

            The max and min values it returns are completely wrong. For the first row in the csv, it returns the max as 71, and the min as 104, which is incorrect.

            I assume your input contains numbers, but since CSV is a text format, the input is being read in as strings. min and max are operating based on string sorting, so max("4", "10") is 4 but max("04", "10") is 10. To solve this, you can either cast each element to Numeric (int, floating point, etc.) before you get the min/max:

            1. Removing an item from a list of length N is O(N) if the list is unordered, because you have to find it.
            2. Removing k items from a list of length N, therefore, is O(kN) if we focus on "reasonable" cases where k << N.

            So I don't see how you could get it down to O(N).
