"WebThat seems the natural way to introduce Dijkstra's algorithm. We can say that we will construct S v 's that reach the respective objectives one edge at a time, selecting the "best" "available" element at every step, i.e., selecting the "unsettled" node that is "nearest" to the source at every step. So, the algorithm is greedy. " - Greedy algorithm questions

WebDec 12, 2024 · Greedy Algorithm: Let n ( x) be the number located at index x. At each jump, jump to the index j that maximizes j + n ( j). In the above example, starting at index 0, we can jump 1 or 2 jumps. If we jump once to index 1, then the objective value is 1 + n ( 1) = 4. If we jump twice to index 2, then the objective value is 2 + n ( 2) = 3.
