It is a question of basic importance whether these estimates could be improved upon with some ingenuity and more careful application of the greedy algorithm or, perhaps, their weakness is a consequence ...
WebThe Greedy Algorithm printable sheet. This problem follows on from Keep it Simple and Egyptian Fractions So far you may have looked at how the Egyptians expressed fractions as the sum of different unit fractions. You may have started by considering fractions with small numerators, such as $\frac{2}{5}$, $\frac{3}{7}$, $\frac{4}{11}$, etc.
