Usually in fractional knapsack once you choose an item you cannot choose it again. In your implementation of select_max_index it seems you always select the highest value/ratio which means you will always use it. In the case of your example: first choice is value=120, weight 30 so ...

So, it's basically the same problem as the 0/1 knapsack problem: n items, each having a weight w_i, and a value v_i, maximise the value of all items but keeping the total weight less than W. However, their is a slight twist: Theamount of items in the knapsack need to be even...

for w in range(1, capacity + 1): if weights[i - 1] <= w: dp[i][w] = max(dp[i - 1][w], dp[i - 1][w - weights[i - 1]] + values[i - 1]) else: dp[i][w] = dp[i - 1][w] return dp[n][capacity] 这段代码中,`weights`和`values`分别代表物品的重量和价值列表...
Algorithm for fractional knapsack 1. W and item have value Viand weight Wi. 2. Rank item by value/weight ratio: Vi/Wi. 3. Thus : Vi/Wi= Vj/Wjfor all i<=Wj. 4. Consider items in order of descending ratio. 5. Take as much of each item is possible. 6. Assume value and weight...

Given a set of items, each with the given weight and profit, determine each number of items in such a combination that the total weight of items is less than the maximum limit of the bag, but the value must be kept as large as possible. Algorithm To Implement the Fractional Knapsack Pro...
Oldest Stephen McConnell 10 years ago There are many ways to solve this problem. This is a pretty good one. However, if a thief has to spend the time working through an algorithm, they won’t be very successful ;) (just a thought as I was reading your good article) 0 Reply Join...
