Sorted by: 3. until robot is at the bottom row: while there's a coin to the right on the same row: go right go down one step go to the right corner. or perhaps more succinctly: If there are coins to the right: go right Otherwise: go down. Edit: To see that the algorithm is optimal in the sense that it requires the fewest total number ... 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 … 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 select … See more
