Question

I could use some help with simply pseudocode for a program in C I'm writing: The program will produce a maze using Prim's algorithm and the idea of a MST (minimal spanning tree). The edges of the gridgraph (of asterisks to represent a sort of GUI) produced will be different everytime because arbitrary (random) weights will be assigned everytime it runs as to produce a different maze everytime (accoring to the input from the user). The gridgraph will always be a perfect square (9, 25, 36, etc.[input from user]), and will be printed to the terminal (ultimately a file, but we'll leave that part out). The only input will be the square number of the random maze fo be made and -1 to quit. Also, the maze entrance will always be the top left of the graph, and the exit will be the bottom right. I have visited many websites with these algorithms but I cannot seem to adapt them as I need them for my program.

Explanation / Answer

hi these algorithms are may be help you for your program

For Perfect Square

1.Random Generated gridGraph Algorithm:

def dense_gnm_random_graph(n, m, seed=None):

    """Returns a `G_{n,m}` random graph.

    In the `G_{n,m}` model, a graph is chosen uniformly at random from the set

    of all graphs with `n` nodes and `m` edges.

    This algorithm should be faster than :func:`gnm_random_graph` for dense

    graphs.

    Parameters

    ----------

    n : int

        The number of nodes.

    m : int

        The number of edges.

    seed : int, optional

        Seed for random number generator (default=None).

    gnm_random_graph()

    """

    mmax=n*(n-1)/2

    if m>=mmax:

        G=complete_graph(n)

    else:

        G=empty_graph(n)

    G.name="dense_gnm_random_graph(%s,%s)"%(n,m)

    if n==1 or m>=mmax:

        return G

    if seed is not None:

        random.seed(seed)

    u=0

    v=1

    t=0

    k=0

    while True:

        if random.randrange(mmax-t)<m-k:

            G.add_edge(u,v)

            k+=1

            if k==m: return G

        t+=1

        v+=1

        if v==n: # go to next row of adjacency matrix

            u+=1

v =u+1
