25. Chess algorithm
Multi-diamond optimization algorithms primarily operate on a greedy principle. Each subsequent diamond tries to maximize its own volume, paying little attention to the space it leaves for the others. This greed can lead to inefficient use of the original rough's space. While various balancing techniques exist—where earlier diamonds yield some of their space to later ones to increase the total value—the problem becomes intractable within a reasonable time as the number of diamonds increases and the rough becomes more complex due to cavities and inclusions. This forces a reliance on the initial luck of the greedy approach.
