Dynamic programming greedy algorithm

WebJan 31, 2014 · @NiklasB. actually his solution is greedy, at each stop he will look for the best option using only the cost .. his solution works fine, except it is not optimal, since he is not considering how much gas exist at every distance and how much can he re-fill with that price make the issue here more complex, and makes a cheaper price-per-gas-unit isn't … WebMay 23, 2024 · The classical greedy approach is the following: While W > 0 pick the largest coin c that is <= W W <- W - c. For example, with C = { 1, 2, 5 } and W = 13, you will pick 5, 5, 2 and 1, and you can show that the minimum number of coins required is indeed 4. However, this algorithm does not always provide an optimal solution.

A greedy algorithm, as the name suggests, always makes the choice that seems to be the best at that moment. This means that it makes a locally-optimal choice in the hope that this choice will lead to a globally-optimal solution.
