Sure, here's the pseudocode for the A* algorithm in LaTeX:
\begin{algorithm}[H]
\SetAlgoLined
\KwIn{start node, goal node}
\KwOut{path from start to goal}
openSet $\gets$ \{start\}\;
cameFrom $\gets$ empty map\;
gScore[start] $\gets$ 0\;
fScore[start] $\gets$ heuristic(start, goal)\;
\While{openSet is not empty}{
current $\gets$ node in openSet with lowest fScore\;
\If{current = goal}{
\Return reconstructPath(cameFrom, goal)\;
}
openSet $\gets$ openSet - \{current\}\;
\For{neighbor of current}{
tentativeGScore $\gets$ gScore[current] + dist(current, neighbor)\;
\If{tentativeGScore $<$ gScore[neighbor]}{
cameFrom[neighbor] $\gets$ current\;
gScore[neighbor] $\gets$ tentativeGScore\;
fScore[neighbor] $\gets$ gScore[neighbor] + heuristic(neighbor, goal)\;
\If{neighbor not in openSet}{
openSet $\gets$ openSet $\cup$ \{neighbor\}\;
}
}
}
}
\Return failure\;
\caption{A* algorithm}
\end{algorithm}
Hope this helps!
