• Greedy algorithm for Egyptian fractions — In mathematics, an Egyptian fraction is a representation of an irreducible fraction as a sum of unit fractions, as e.g. 5/6 = 1/2 + 1/3. As the name indicates, these representations have been used as long ago as ancient Egypt, but the first… …   Wikipedia

• Greedy algorithm — A greedy algorithm is any algorithm that follows the problem solving metaheuristic of making the locally optimum choice at each stage Paul E. Black, greedy algorithm in Dictionary of Algorithms and Data Structures [online] , U.S. National… …   Wikipedia

• Greedy randomized adaptive search procedure — The greedy randomized adaptive search procedure (also known as GRASP) is a metaheuristic algorithm commonly applied to combinatorial optimization problems. GRASP typically consists of iterations made up from successive constructions of a greedy… …   Wikipedia
