Web7 de abr. de 2024 · Egyptian Fraction representation of 6/14 is 1/3 + 1/11 + 1/231. The Greedy algorithm works because a fraction is always reduced to a form where denominator is greater than numerator and numerator doesn’t divide denominator. For such reduced forms, the highlighted recursive call is made for reduced numerator. Web28 de nov. de 2014 · A greedy algorithm would pick objects of highest density and put them in until the knapsack is full.
