WebMay 24, 2024 · Uniform cost is an uninformed search algorithm when Best First and A* search algorithms are informed search algorithms. Informed means that it uses a heuristic function for deciding the expanding node. Difference between best first search and A* is that best first uses f(n) = h(n) for expanding and A* uses f(n) = g(n)+h(n) for choosing 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
