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. WebThe Grassfire algorithm is a simple algorithm that works by propagating a "wave" from the start node until it reaches the goal node. The wave starts at the start node with a value of zero and propagates outwards to adjacent nodes, increasing the value of each node it passes through by one. The process continues until the wave reaches the goal ...
