frosja888 [35]

Answer:

Following are the response to the given question:

Explanation:

The glamorous objective is to examine the items (as being the most valuable and "cheapest" items are chosen) while no item is selectable - in other words, the loading can be reached.

Assume that such a strategy also isn't optimum, this is that there is the set of items not including one of the selfish strategy items (say, i-th item), but instead a heavy, less valuable item j, with j > i and is optimal.

As W_i < w_j, the i-th item may be substituted by the j-th item, as well as the overall load is still sustainable. Moreover, because v_i>v_j and this strategy is better, our total profit has dropped. Contradiction.
