CSP Recursive Calls Fail with with Range(a,b) but not Explicit Range

Asked 2022-Jan-15 at 20:27

Sudoku is a well known CSP and, in this case, LC problem. I don't need the solution, which follows.

My question is why does self.DOMAIN = "123456789" (line #4) work, whereas self.DOMAIN = map(str, range(1, 10)) (line #5) does not? Are they not equivalent?

You are suffering confusion between "generator" and "container". Consult type( ... ) to tell the difference between them.

Python generators are "lazy", for excellent technical reasons. Sometimes we can get away with just evaluating the first K items of an infinite generator.

In your method you want everything greedily pulled out, and then stored in a container. The conventional way to phrase this is to wrap map with list:

QUESTION

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.

I can't find an appropriate answer in previous asked questions. Below is a Unit Test code for my Sudoku-solver. In this app i have an interface 'ISudokuStrategy'.

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:

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!

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.
