path finding - Understanding this implementation of A-star algorithm in Python -


I'm new to Python I have this code I have

its A-star algorithm code. I wanted to know how it creates obstacles. Actually I have a black and white image. My task is to reach the end point from start point to avoid white bars. Finding the path-find algorithm in the function pathFind () < P>

Code> is well commented and decomposed If you have some specific confusions, let us know what it is.

I recommend that you suggest reducing the parameters (M, N) after a 4x5 or 5x6 then move through your execution, either PDB debugger (single-phase at important points Or set breakpoints), or hacking in many print statements as per your requirement: 

  # matrix matrix n = 30 # horizontal size m = 30 # vertical size   
 First try to give your own custom maps that it Ase works ( # to modify fillout) map matrix ...  lines). Then run it interactive in the debugger.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

Please help! Note: This is derived from the normal routine and is a simplified code. I can no...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
