   As mentioned earlier, the greedy algorithm doesn't always produce the optimal solution. This is the major disadvantage of the algorithm For example, suppose we want to find the longest path in the graph below from root to leaf. Let's use the greedy algorithm here. Greedy Approach 1. Let's start with the root node 20. The weight of the right child i...

   To begin with, the solution set (containing answers) is empty.

   At each step, an item is added to the solution set until a solution is reached.

   If the solution set is feasible, the current item is kept.

   Else, the item is rejected and never considered again.

   Solution: 1. Create an empty solution-set = { }. Available coins are {5, 2, 1}. 2. We are supposed to find the sum = 18. Let's start with sum = 0. 3. Always select the coin with the largest value (i.e. 5) until the sum > 18. (When we select the largest value at each step, we hope to reach the destination faster. This concept is called greedy choice...

   Does greedy algorithm give the best solution for every problem?

   • Greedy algorithm makes decisions based on the information available at each phase without considering the broader problem. So, there might be a possibility that the greedy solution does not give the best solution for every problem. It follows the local optimum choice at each stage with a intend of finding the global optimum.

   What is greedy method?

   • Let's understand through some terms. The Greedy method is the simplest and straightforward approach. It is not an algorithm, but it is a technique. The main function of this approach is that the decision is taken on the basis of the currently available information.

   How to solve a problem using a greedy approach?

   • If the optimal overall solution to the problem corresponds to the optimal solution to its subproblems, then the problem can be solved using a greedy approach. This property is called optimal substructure. The algorithm is easier to describe. This algorithm can perform better than other algorithms (but, not in all cases).

   What is a greedy optimization algorithm?

   • Greedy algorithms are often used as a first step in solving optimization problems, because they provide a good starting point for more complex optimization algorithms. Greedy algorithms can be used in conjunction with other optimization algorithms, such as local search or simulated annealing, to improve the quality of the solution.

   Can greedy algorithms solve combinatorial optimization problems?

   • Combinatorial optimization: Greedy algorithms can be used to solve combinatorial optimization problems, such as the traveling salesman problem, graph coloring, and scheduling. Although these problems are typically NP-hard, greedy algorithms can often provide close-to-optimal solutions that are practical and efficient.
