Backtracking
Index N-Queens Problem Hamiltonian Circuit Problem Subset-Sum Problem Branch and Bound Assignment Problem Knapsack Problem Traveling Salesperson Problem Backtracking is an algorithmic method to solve a problem in an additional way. It uses a recursive approach to explain the problems. We can say that backtracking is needed to find all possible combinations to solve an optimization problem. Backtracking is a systematic way of trying out different sequences of decisions until we find one that works. Suppose we have to make a series of decisions, among various choices, where we don't have enough information to know what to choose and each decision leads to a new set of choices, Some sequence of choices (possibly more than one) may be a solution to our problem Backtracking is a methodical way of trying out various seq...
