Q: How to speed up this numba based decision tree?

zhenlingcnIn order to improve the performance of this code fragment, I have speeded up some code fragments by using the numba. However, a frustrating thing is that the performance of this decision tree is bad. For example, in the below code fragment, the performance of the decision tree is nearly 70 times ...

The function below works as expected. I just want to know if my code catch-all edge cases? I don't want, even 1 second that will request will...

If your code doesn't work well enough (takes too long, too much RAM), then it's a toss up between here (mostly algorithms related), Computer Science (if it's more purely theoretical question) and Code Review (if you have a lot of code and it's nuanced). — Nuclearman 36 secs ago

Q: Randomly selected values from predetermined arrays must add up to specific input value

FinKIm trying to write a Python code that adds up random integers from specific lists to a specific value. My code picks a random variable from list POP and in that variable it picks an integer. It can only pick every item from list POP once. Thus I need a sequence that adds up to the input variable ...

Q: Randomly selected integers from predetermined lists add up to specific input value

FinKHello im trying to write a Python code that selects integers from arrays up to a certain value. I wrote this code however the code uses every list once (as is intended). But sometimes it is still below the input value and has no more options to choose from. For example if i say WantedNumber is 15...

Q: Event tracking system

Daniel JordanovI am a learning C++ programming and just learned about basic OOP and decided to create a simple project to test my understanding and practice what've learned. The idea I came up is a event tracking system where you add events into a calendar and then you get all of your events displayer. I have 2...

Q: Django: view to output data into a dashboard

dassoukiI'm a beginner in Django3 and just wrote an overview function to pass on some data to the template in a context variable. I am definitely passing a lot more than I should as I only need only a few fields from each of these variables. Also, it might not be the most Django-esque way of doing things...

If you algorithm can handle k = n = 500, m=1e6, you pass, but you can't use >50GB RAM, and there should be no noticeable memory leaks. This is my goal; it's why I didn't ask on Code Review - the only Python hope is if Numpy did it in C. Or if there's a clever math algorithm. — OverLordGoldDragon 9 secs ago

@Divakar Nope, pick any. If you plan on implementing this, I really doubt you can manage something in Python unless Numpy exposes C tools; I can (and eventually will if nothing is found here) open a Code Review question on this, in C or C++. — OverLordGoldDragon 56 secs ago

Q: constexpr local variable causes compile fail
