Backtracking Backtracking is a general algorithm for finding all (or some) solutions to some computational problems, notably constraint satisfaction problems, that incrementally builds candidates to the solutions, and abandons each partial candidate ("backtracks") … WebStart by putting one of the vertexes of the graph on the stack's top. Put the top item of the stack and add it to the visited vertex list. Create a list of all the adjacent nodes of the vertex and then add those nodes to the unvisited at the top of the stack. Keep repeating steps 2 and 3, and the stack becomes empty.
