QUESTION

A* algorithm TypeError: cannot unpack non-iterable int object

Asked 2021-Oct-07 at 11:06

This is the python code which uses A* algorithm for finding solution for 8 puzzle problems, I got some error messages, how can I fix it?(The error message is under the code)

There are several object-oriented programming concepts for Problems class, Node class that are implemented to express the problem solution search that you need to understand in order to make the Python program complete. The priority queue is to make the nodes to be explored to be sorted according to their f-evaluation function score and return the min one as the first node to be searched next.

There is also a memorize function to memorize the heuristic value of state as a look-up table so that you don’t need to calculate the redundant computing of heuristic estimation value, so you can ignore it at this point if you don’t understand.

The components you need to implement is to make the abstract part of the program realizable for 8 -puzzle with the successor methods attached to a problem class which consists of initial state and goal state. Make sure the program can run correctly to generate the solution sequence that move the empty tile so that the 8-puzzle can move "Up", "Down", "Left", "Right", from initial state to goal state.

I got some error messages, how can I fix it?

There is one error message, The pieces of codes you get in the error message are the stack trace, which might help you to know how the execution got at the final point where the error occurred. In this case that is not so important. The essence of the error is this:

for (act,n) in problem.successor(self.state)

TypeError: cannot unpack non-iterable int object

So this means that the successor method returned an int instead of a list.

Looking at the code for successor, I notice that it intends to return a list called reachable, but there is a return statement right in the middle of the code, leaving the largest part of that code unexecuted (so-called "dead code"):

Yes, because you would get the same value only if all misplaced tiles are just next to their correct place (i.e. manhattan distance = 1). In all other cases the manhattan distance for a misplaced tile is > 1.

QUESTION

8 Puzzle: Sorting STL Heap/Priorirty Queue containing pointers to object by member variable

Asked 2020-Mar-31 at 07:25

I'm working on implementing a Best-First Search algorithm to solve an 8-Puzzle problem for an assignment. Based on the requirements, it must be implemented using a (min) Priority Queue or Heap located in the Standard Template Library (STL).

I understand that it would be useful to use either data structure to organise expanded puzzle states by best heuristic cost (ie. the smallest cost).
