WebMar 24, 2024 · We can use the depth-first search to solve puzzles with only one solution or to find connected components. It’s also a default algorithm for finding cycles in a graph. Moreover, it’s a more useful general graph search than the breadth-first search because it’s more space-efficient. 3. Backtracking. WebMay 22, 2024 · Setting the Scene. Many problems in Graph Theory could be represented using grids because interestingly grids are a form of implicit graph. We can determine the neighbors of our current location by searching within the grid. A type of problem where we find the shortest path in a grid is solving a maze, like below.
