If you don't need to do recursion, then I suggest change the knapsack into a combination of loops, which will make identifying index positions of the final result much easier. If the constraint condition is not satisfied after t is placed, then proceed to here, and then judge if the current value plus the remaining value are not optimal, then there is no need to proceed, Used to record a certain retrospective situation, These goods could be put in the shopping car, Print the placement of all items, if it is 1, it means it is put in, if it is 0 it means it is not put in. Branch and Bound Method-Branch and bound is a state-space search method in which all the children of a node are generated before expending any of its children. Backtracking can be described as an organized exhaustive which offers avoids searching for all possibilities. Knapsack Problem -- Backtracking Given n positive weights w i, n positive profits p i , and a positive number M which is the knapsack capacity, the 0/1 knapsack problem calls for choosing a subset of the weights such that S i = 1 to k w i x i M and S i = 1 to k p i x i is maximizd The x's constitute a zero-one valued vector. Backtracking is also a way of solving the problem of space. The knapsack problem has several variations. Example: Say we have a knapsack of capacity 5 kg. Required fields are marked *.
