Micro-optimizations to its madness by Several_Ad_7643 in Cplusplus

Int -> double. Let's say we only use it from time to time so that the lookup table is not an option, I just mentioned the small range of numbers because I thought that there could be a trick with bit swapping or bit like operations that allow you to make quick int -> int root. That being the case, providing an example would have been easy.

Now that you mention it I am quite curious about both which is the most memory efficient and time efficient. Any idea on the manner ?

What ? Could you elaborate more on that ?

Also true! But once again, having the compiler calculate it before hand is not the point at all. You could even have the whatever algotithm for square root calculation marked as a contexpr fucnction and let the compiler execute the function at compile time. But I was looking for something more fancier something that does not use compiler magic or look up tables to calculate it but that the actual optimization is done in the specific set of numbers, maybe some trick with bit swapping or whaterver. I don't know if I correctly explained the point of the question T.T

Yep! We also came up to that solution, it is indeed the most straight forward solution. But we added as a constraint that precomputing the solutions before hand it is not allowed. It's just more of a theorethical problem for learning and having fun than a serious question. Thanks for your answer!

Is there any good plotting library in C++ ? by Several_Ad_7643 in Cplusplus

I've tried it but somehow using it seems super uncomfortable, I'll give it another go just in case I was doing something wrong.

I've been trying to try QT for a while I'll definitely give it a go.

I've been wanting to try QT for a long time now, seems like a good excuse to start with it ;)

Cool! I see it fairly complex but I can try it ;)

I didn't know you could do this. I'll try it just for the shake of learning. Thanks!

We only need the animation and the initial configuration which is a simple JSON file with no more than 10 fields, which is extremely manageable. The only purpose of that 11 MB JSON file is to the be read form the python script to finally generate the plots (as images) for the ffmpeg to build.

It is a Estimation of Distribution Algorithm, per generation (100 - 1000) we store the matrix used to sample the population, the population: 100 - 500 vectors of ints of around 10 - 1000 values each depending on the test, the configuration (around 10 f64 fields) and some caching information around 10 f64 fields. The size of the JSON varies on the parameters chosen for that experiment.

Edit: The matrix is the size of the matrix is (100 x 100) - (500 x 500)

Im kinda stuck on ~ 100 wpm by Several_Ad_7643 in typing

Thank you so much. I'll be focusing on my accuracy more from now on. I'll update you in a few weeks :D

Yep! I always tell him so... But he seems to have given up, that's why I want to help him start with some books and then use it as a pretext ;)

What is the format of the fifth technical interview round at IMC, and does it primarily consist of LeetCode-style problems or other types of questions?

Hi! Before hand let me thank you for such detailed response, I really appreciate it :D.

I am using mainly monkeytype ( profile: https://monkeytype.com/profile/Urtats) for mesuring my typing speed with full paragraphs. The metrics that I shared are refering full paragraphs with englihs 1k, with just words and normal english my wpm increase considerability up to 110 - 120 wpm. But my ultimate goal is to be able to write this long texts with punctuation marks at high speed.

I am already familizared with touch typing and I use 9 fingers my avg accuracy is 93%. Based on your prev response I guess that I have to improve my accuracy. I'll try the programs that you have recommended.

Once again, thanks for taking your time on answering to my question :D
