WebGreedy Best-First Search when EHC Fails. As in FF, Marvin resorts to best-first search if EHC proves unable to find a solution. This approach maintains the completeness of the … A greedy algorithm is an approach for solving a problem by selecting the best option available at the moment. It doesn't worry whether the current best result will bring the overall optimal result. The algorithm never reverses the earlier decision even if the choice is wrong. It works in a top-down approach. See more 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 … See more 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 … See more
