WebGrassfire Algorithm This path spreads like fire. The destination cell is marked 0 and the adjacent cells are marked in an increasing number sequence until we reach the starting cell. WebOne such algorithm is the Wavefront or Grassfire Algorithm. Set-Up This algorithm starts with a grid representation of the environment (2D array). In this grid, obstacles are marked with a value of -1 to indicate they are non- navigable. Zeroes indicate unexplored or possibly unreachable positions.
