was asked a similar problem on a job interview lately and i struggle to come up with a more efficient solution. The problem’s Rules, assuming travel is done through x axis, left to right for simplicity: In each move you must travel a single index to the right. You are allowed to start at any ..
You are given a NxM grid and you start at cell (1,1) . At each cell (x,y) you can move to cell (x+y,y) or (x,x+y). Find the minimum number of steps to reach the (N,M). Input – Integer N and M. Output- Minimum number of steps to reach (N,M). -1 if it is not possible ..
Context: My code use boost dijkstra algorithm to perform pathfinding on 13.4M vertices/33M edges graph. While doing profiling, I notice that 60% of dijkstra calls were dominated by a call that initialize a IndexInHeapMap during dijkstra_shortest_paths_no_color_map_no_init. I suspect that it take so long because of the graph size Is there a way to avoid/reduce this ..
I want to add a css file to my program in gtkmm library by Gtk::CssProvider. But when compiling it gives me an error not to find file. But the file is in exactly the same direction! program code: auto styleProvider = Gtk::CssProvider::create(); styleProvider->load_from_resource("/res/style.css"); path: ├── build │ ├── build.ninja │ ├── ChessAP │ ├── [email protected] ..
I’m making a program that can take an image of a maze and output a highlighted path on top of the original image. The image I’m using here is . I am able to correctly read the image’s pixel values as this is what is printed out (B is black and W is white) BBBWBBBBBB ..
I’ve looked over several different implementations of A*. The current one I am using is based off of the pseudocode from the Wikipedia page. It finds the path but then the monster doesn’t move so I’m guessing it doesn’t work. It’s also incredibly slow. This is inside the update function which is called after the ..
I am building a simple path finding algorithm for demonstration purposes. I need to select an appropriate data structure and algorithm for the path finding algorithm and I have selected A* Search. My question now is do I use Graph or Vectors? I need help understanding when to use Graphs and when to use Vectors. ..
I’m trying to develop a Pathfinding Visualizer GUI using Qt Creator, but I’m quite new with the IDE. At this point, I have a basic 10×10 grid of push button cells in a window that resembles a game of Minesweeper. So my question is this: What’s the best way to go about changing the color ..
I’m trying to implement an A* algorithm for pathfinding in my 3D grid. I’ve been following a tutorial but I’m not getting a valid path. I’ve stepped through my code to find out what’s going on, but I don’t know how to solve the problem. For the most basic test I’m just using a 2-D ..
currently a homework that I am working on aims to simulate a flightMap system that has reads cities and flights from a txt file and that has a main searching algorithm that finds paths from a departure city to a destination city through flights. The non-recursive search algorithm that uses stack adt that I wrote ..
