The above result was proved by Edgar Gilbert for general code using the greedy method as here.
2.
Two main approaches for solving the optimization problem are : 1 ) greedy methods, such as proximal gradient optimization methods.
3.
He includes the greedy method as a last resort for situations when several simpler methods fail; see Egyptian fraction for a more detailed listing of these methods.
4.
However, in his dissertation he proved that the greedy method for set cover has a lower bound of 1-1 / e ~ 63 % of the optimal.
5.
As Salzer ( 1948 ) details, the greedy method, and extensions of it for the approximation of irrational numbers, have been rediscovered several times by modern mathematicians, earliest and most notably by; see for instance and.
