The primary di culty lies in solving the highly non-convex optimization problems resulting from the neural network discretization, which are di cult to treat both theoretically and practically. It is Greedy algorithms can be characterized as being 'short sighted', and also as 'non-recoverable'. They are ideal only for problems that have an 'optimal substructure'. Despite this, for many simple problems, the best-suited algorithms are greedy. It is important, however, to note that the greedy algorithm can be … See more A greedy algorithm is any algorithm that follows the problem-solving heuristic of making the locally optimal choice at each stage. In many problems, a greedy strategy does not produce an optimal solution, but a … See more Greedy algorithms have a long history of study in combinatorial optimization and theoretical computer science. Greedy heuristics are known to produce suboptimal results on many problems, and so natural questions are: • For … See more • The activity selection problem is characteristic of this class of problems, where the goal is to pick the maximum number of activities … See more • "Greedy algorithm", Encyclopedia of Mathematics, EMS Press, 2001 [1994] • Gift, Noah.
