Create a Python program which reads a text file where each line contains the coordinates of a multidimensional point, and then looks for the closest pair of points in the file. If the program has found the closest pair of points, it should output the line numbers of the two closest points. The text file contains one point per line. The coordinate values are separated by a tabulator character. The coordinate values are not necessarily integers. In case of a floating point coordinate value the decimal separator is a period. Remarks: •The distance of two points is the Euclidean distance, that is the square root of the sum of squares of the differences of corresponding coordinate values: sqrt ( sum_i ( ( x_i – y_i) ^2 ) ) What we expect: •The source code. We prefer concise and easy to read code. •A brief summary of the solution, for example, the asymptotical running time of the algorithm, limitations, usage instructions and any other comments. •One or more test files created by you.

Hi, if usage of Python is not a requirement i can create this simple tool as Windows/Linux console application. My solution will use combinations first, to determine all possible pairs of points. I.e. 4 lines in text file means 6 possible pairs: 1 and 2, 1 and 3, 1 and 4, 2 and 3, 2 and 4, 3 and 4 Then calculate distance for each pair of points. I only need to know what to do if there is more than a single pair with same calculated distance? Input file must be fully loaded first to determine combinations count (pairs of points) and this will be the slowest part of program. By "slowest" i mean depending on file size - probably just a few additional milliseconds for small files. Combination + distance calculation algorithm will be very fast and not take much resources. I assume dimension is constant for a single input file (1D or 2D or 3D etc. but not mixed, however this can be checked and error will be shown).

I know Python very well. This is clear enough task, I will use Python 3 by default, so if Python 2 is needed - please tell this.

Hello, I am very intrested to do this project for you. I am studing software engineering and I have couple of years expirience in this feild. This is very important to me because this is my first project and I would like to have a positive review on start. As you can see my bid is pretty low, that is because I really need this first job on freelancer and I would be very grateful if you could help me with that. I will do my best to satisfy your every need. I was free to finish my solution for your project. Complexity of program is n^2, but I also did n (log n )but only for two dimensional points. It would be great if you could look it up and let me know what do you think. I can send you part of my main code and if you like it I can send you the whole code immediately. As i said, I am new on this site and I need an opportunity to prove myself. Thank you very much for understanding. Looking forward to working with you.

I was a Java programmer. Now I'am a data scientist using R and Python. I plan to use divide and conquer paradigm (O(n*log(n)) performance guarantee) to solve this problem. Looking forward to your reply.

will give python code which will do reading of textfile parsing the file to calculate the euclidian distance. find near by points. group them and print line numbers on the parsed file. Will give well commented code and running complexity. will give unit test files.

I have excellent python knowledge, including how to open and parse a file, then use its contents. If desired, I could write a function to also output the results of the program to a file.
