Welcome to PathVisor
Pick an algorithm to start.
Click the Start (🟦) or End (🟧) node once to change its position.
Use the Player to control the speed and execution of the algorithm. Click the right and left arrows for step-by-step analysis.
Select Walls or Weights from the menu and draw them on the grid.
Walls represent impassable obstacles that the algorithm cannot traverse, forcing it to avoid them.
Weights are nodes that the algorithm can pass through, but with additional costs. A tile with a “2” has a low cost. A tile with a “9” however has a higher cost, making it less desirable for the algorithm to choose, unless it’s the only optimal path. The algorithm prefers to choose paths with lower costs.
Note: Only the Dijkstra and A-star algorithms work with weighted nodes; other algorithms treat them as regular nodes.
Visited nodes can't be modified. To reset the grid, click the button on the bottom right.
