Roni SaibaI have tried to code a genetic algorithm to guess the coefficients of a degree 4 polynomial. The information initially provided is values of y = f(x) for different x using the original polynomial. I then generate 100 polynomials with randomly selected coefficients. These polynomials are then rank...

If you don't know whether your code is written correctly, test it. We expect this before you post. If you need code review, then post to CodeReview.StackExchange.com -- neither of these requests is appropriate for Stack Overflow. — Prune 10 secs ago

In the fourth lesson of the series, we’ll talk about the matrix representation of the linear regression problem. In the process, we’ll discuss the basics of matrix multiplication. We’ll also see how this mathematical understanding can prepare us to make sense of error messages that we might encounter when fitting a model in Python. Hereā€¦

@Duga Answer might've been premature.
If anyone that actually understands Rxjs would take a look, please.

Maybe with a reproducible example (e.g., a small simulated dataset that can grow and PUClic being defined), you may get more responses. Regardless, this may be better at Code Review or consulting with someone who can refactor your code. I am removing data.table tag as this is more of a question of "How do I improve performance of this function" rather than something dealing with data.tableCole 27 secs ago
