Sample Program Code – Robotic Project C++

The A* algorithm is a path-finding algorithm that finds the shortest path between two points in a graph. It is a greedy algorithm, which means that it makes the best possible choice at each step, without considering the future. This makes it efficient, but it is not guaranteed to find the shortest path.

The A* algorithm works by maintaining a priority queue of nodes that are still being considered. The priority queue is ordered by the estimated cost of the path from the start node to the current node, plus the estimated cost of the path from the current node to the goal node.

At each step, the A* algorithm removes the node with the lowest priority from the priority queue and adds its neighbors to the priority queue. If a neighbor is already in the priority queue, its priority is updated if the new estimated cost is lower.

The A* algorithm terminates when the goal node is found. The path from the start node to the goal node can be found by following the pointers from the goal node to its parent node, and so on, back to the start node.

The following code implements the A* algorithm in C++. The code takes a two-dimensional grid as input, and it outputs the shortest path from the start node to the goal node.

#include
#include
#include

using namespace std;

// A node in the grid.
struct Node {
int x;
int y;
int g; // The cost of the path from the start node to this node.
int h; // The estimated cost of the path from this node to the goal node.
Node* parent; // The parent node of this node.
};

// A priority queue that orders nodes by their priority.
struct PriorityQueue {
vector<Node*> nodes;

// Insert a node into the priority queue.
void insert(Node* node) {
nodes.push_back(node);
sort(nodes.begin(), nodes.end(), [](Node* a, Node* b) {
return a->h + a->g < b->h + b->g;
});
}

// Remove the node with the lowest priority from the priority queue.
Node* remove() {
Node* node = nodes.front();
nodes.erase(nodes.begin());
return node;
}

// Check if the priority queue is empty.
bool empty() {
return nodes.empty();
}
};

// A function to initialize the grid.
void initializeGrid(vector<vector>& grid) {
for (int i = 0; i < grid.size(); i++) {
for (int j = 0; j < grid[i].size(); j++) {
grid[i][j] = 0;
}
}
}

// A function to check if a node is valid.
bool isValid(vector<vector>& grid, int x, int y) {
return (x >= 0 && x < grid.size() && y >= 0 && y < grid[0].size() && grid[x][y] == 0); } // A function to calculate the estimated cost of the path from a node to the goal node. int calculateH(Node* node, Node* goal) { return abs(node->x - goal->x) + abs(node->y - goal->y);
}

// A function to find the shortest path from the start node to the goal node.
Node* findPath(vector<vector>& grid, Node* start, Node* goal) {
// Initialize the priority queue.
PriorityQueue queue;
queue.insert(start);

// Create a set to keep track of the nodes that have already been visited.
set<Node*> visited;

// While the priority queue is not empty...
while (!queue.empty()) {
// Remove the node with the lowest priority from the priority queue.
Node* node = queue.remove();

// If the node is the goal node, then we have found the shortest path.
if (node == goal) {
return node;
}

// If the node has not already been visited...
if (visited.find(node) == visited.end()) {
// Mark the node as visited.
visited.insert(node);
