PyPy vs. CPython 3.8 - Difference in "number of iterations" with the same code?

Asked 2021-Jan-21 at 01:14

I've stumbled upon an interesting phenomenon while I was tinkering with my sudoku solving algorithm written in Python.

I'm counting iterations in the backtracking algorithm and saving the number in a log file. (The algorithm seems to be completely deterministic, hence I'm intrigued by the sudden increase in the number of iterations to get the same output.)

Now the interesting part is:

When I tried to run the same code with PyPy (3.7-v7.3.3-win32) instead of Python 3.8 (64bit) the number of iterations about doubled when running with PyPy to 629505 from the 362073 with running with CPython.

My question is: Does anyone know why is this difference in the number of iterations?

I think you're enumerating over sets at line 117. This order is unspecified, i.e. arbitrary, in CPython. In PyPy you get the order in which you've put the items in the set.

Well, it's you code, so... why do you? We cannot tell you why your code looks like it does.

What you should do, is make it a variable local to your unit test:

Sudoku Backtracking with Solution Counter

ANSWER

Answered 2020-May-28 at 14:26

The issue with your code is that it stops after it finds the first solution - more specifically, your code will never change an assigned value to a cell unless it is wrong. This is standard backtracking that you've implemented. What you need to do is, once you find one solution, you need to force your code to use other values and see if it also returns a valid solution.

Let's say this is the last row of your sudoku (where you're missing the last value), and your count is currently 0 (i.e. no solution so far):

Problem on return matrix algorithm Python

Asked 2020-May-11 at 15:57

I'm practising my little Python skills by programming a Sudoku-Solver Algorithm.

I implemented unit test to. Now I have implemented the solver, that returns a solved matrix of the Sudoku, and I check it in the unit tests.

But the result var assigned by the return of the solver result None. I made some Breakpoints and at the end of the solver the return value ist the right solved matrix. Can someone give me a hint in which point I'm missing something?

Thanks a lot!

Answered 2020-May-11 at 15:57

I found the answer. The problem was that the algorithm do not know when there are some free cells to fill. So the recursion do not stop at the end of the solution. If I insert a control that checks if there are the free cells the algorithm works.

Cryptogram Puzzle with Prolog CLPFD

Asked 2018-Apr-16 at 08:04

I recently found a small game on the Google Play app store called Cryptogram. There are dozens of apps similar to this one. The idea is to match the number to the colors such that all of the equations sound true.

I was able to get through problems 1-8 and problem 10 fairly quickly by hand, but problem 9 has proven to be more difficult for me.

Problem 9

After some time tinkering and guessing, I gave up and decided to program a solution. I have used Prolog/Datalog for some small tasks as an undergrad as well as some Project Euler problems. Previously I had seen the 15 line Sudoku solver that uses Prolog's Constraint Logic Programming over Finite Domains (clpfd) library, and I decided to give it a go myself. I'm using SWI-Prolog.

How to detect document from a picture in opencv?

Asked 2017-Feb-07 at 01:28

I am trying to design an app similar to camscanner. For that, I have to take an image and then find the document in that. I started off with the code described here - http://opencvpython.blogspot.in/2012/06/sudoku-solver-part-2.html

I found the contours and the rectangular contour with max area should be the required document. For every contour, I am finding an approximate closed PolyDP. Of all the polyDP of size 4, the one with max area should be the required document. However, this method is not working.

The input image for the process is this

I tried to print the contour with max area and this resulted in this (Contour inside letter 'C')

Code:

ANSWER

Answered 2017-Feb-05 at 20:16

I would do it like this:

Do preprocessing like blur / canny
Extract all lines from the image using the hough line transform (open cv doc).
Use the 4 strongest lines
Try to construct the contour of the document using the four lines

Right now I do not have an OpenCV installed so I cannot try this approach but maybe it leads you in the right directon.
