What is the condition to determine if an item shouldn't be added to the knapsack?
What is the condition to determine if an item shouldn't be added to the knapsack?
- The weight of the item equals the weight of the candidate
- The weight of the item plus the weight of the candidate exceeds the capacity (correct)
- The weight of the item plus the weight of the candidate is less than the capacity
- The weight of the item is more than the weight of the candidate
Why must an item be extended if it can extend a candidate?
Why must an item be extended if it can extend a candidate?
- To potentially reach a higher value solution (correct)
- To ensure the current best solution remains unchanged
- To prevent the solution from exceeding the capacity
- Because an extended candidate always leads to a better solution
What does it mean when an item can extend a candidate towards a solution?
What does it mean when an item can extend a candidate towards a solution?
- The capacity is less than both the item's weight and the candidate's weight
- The sum of their weights doesn't exceed the capacity (correct)
- The item has a higher weight than the candidate
- The item's value is lower than the candidate's value
