I have this algorithm for travelling salesman problem, it solves for Nodes = 33800 in 20 minutes. I would like to have it optimized more. Please if you find better code lines alternatives, unnecessary chuncks, I d really appreciate it. The following code solves this problem: https://www.docdroid....

I'm practicing refactoring and Java 8 with very simple examples of Powerball. I used LottoRank enum to write a function that returns the matched LottoRank based on the number of matches and bonus balls. The 1st place is when you hit all 6 numbers. The 2nd place is when you hit 5 with bonus ball...

This class allows for setting conditions on setting a property. it has success and failure callback, you can modify/transform the input in some way or check/validate it against a known value. This class Takes an input type, creates a private field to represent that type, optionally it can take an...

I been trying to implement a text processor in JavaScript that can handle 4 different types of operations: append, backspace, undo, redo. The input for this text processor is an array of arraries of a single element or tuples. For example: const input = [['APPEND', 'Hey'], ['APPEND', ' there'],...

As a Haskell beginner I'm currently playing around the IO monad and prepared simple program which gets from the user two information: URL (http) Output file path Then it performs GET request to the provided URL and stores the result in the selected file. HTTP status code of the response is disp...

I would like to generate Millions of Random String and Hashes in Java fast as possible. For the moment, @Turing85 gave me a pretty good code who was pretty fast only 5 sec for 50M of random String but the next problem to which I am confronted is the slowness when I hash my passwords in my String....

I implemented a convenience class to time code execution and print it to the user. This is part of a bigger project that will be distributed to external users. I was interested in implementing this myself, so I'm not looking for an external module or similiar. Docstrings are omitted here, the fun...

Likelihoods Now let us start implementing the actual classifier. We begin with a multinomial likelihood function. Implement function multinomial_likelihood(probs, freqs) that takes two arguments: probs are dictionary of probabilities of each character (in some language) and freqs is dictionary of...

I'm beginner on doing programming and just started learning C language. Then, i decide to make Tic-Tac-Toe as my first program. My Tic-Tac-Toe summary: User can choose whether want to play 2 player or against computer. For computer player, i use Minimax Algorithm so it's not easy for user to win,...

I am new to C and programming in general and currently going through CS50 and learning C. I have a scrabble game running which takes player 1 and player 2's input, calculates the score. Whichever player has the highest score is the winner or a tie if the score is the same. It all seems to work ho...

I have the following code which requests data from an API but there is a limit to the amount of requests that can be made at the same time, thus I have added a pause code for when the limit is reached: def requests(self): while a < self.dataneeds: do requests... if self.requested ...

In response to easy function from a pair of 32-bit ints to a single 64-bit int that preserves rotational order by Aubrey da Cunha, Mark Dickinson presented a pair of mutually recursive functions instrumental to that end. The almost repetition irritates me: Below the almost original code and a sta...

I am fairly new to C++ and I was wondering if there is anything I can improve in this code(perf, readability)? Thanks. This is the full code: Github Link I will post the parser and eval here(the rest is on the github): std::vector<std::variant<double, std::string>> s_yard(const std::string& str, ...

I have written a Common Lisp implementation of Scheme's s-expression comments (SRFI 62): (eval-when (:compile-toplevel :load-toplevel :execute) (defun handle-s-expression-comment (stream char n) (declare (ignore char)) (when n (error "Infix parameter not a...

How could i improve the following code. This part was easy to implement but there is a lot of redondancy and i use pandas to return as dict which seems quite odd. def pipeline_place_details(place_id, fields, lang): """Return a dataframe with useful information Args: place_id ([st...

I'm trying to make a console application to sort and delete duplicate image files. I have a folder with about 20000 images which take up roughly 70GB of space. I wrote the following script and it seems to work fine, but the issue is that my PC runs out of available RAM memory (it has 16GB) withou...

I have a table data stored in a database ships.db, the data are informations of tracked ships hourly. The table data looks like this. time | shipId | longitude | latitude --------------------------------------------------------------------- 00:00:00 1 xx.xxxx yy...

This is an experiment to see what's involved in adding new functional capability to the Common Lisp baseline. In this case, it's adding a sequence function to select elements from a sequence satisfying a predicate. I don't regard such baseline functions as simple utilities, because they seem more...

I am processing an unknown "length" of generator object. I have to keep things "lazy" because of memory management. The processing is compute heavy, so writing it multiproc style is the solution (or at least it seems for me). I have solved this problem of multiproc on generator object with a com...
