Category "path-finding"

I am confused between shortest path finding algorithm and graph traversing algorithm

My understanding is that BFS and DFS are graph traversing algorithm while other algorithms like A* and dijkstra are for finding shortest path between two nodes

Longest path on a grid, without revisiting grid cells

I am looking for an algorithm to fidn the longest path between two points on a grid, with the added restriction that you cannot revisit a cell on the grid. (Als
