WebDec 5, 2024 · Greedy algorithm on a number choice game. There is a game with a sequence of n numbers (a1, a2, a3,..,an) and two players. Players take numbers from the sequence; on each turn the player can choose either the first or last number in the sequence. When the sequence is emptied, the player with the larger total wins; if equal, …

But the problem is the greedy algorithm gives me a result that colored vertices (represent routs) those have same origin route (suppose AB route is V1 vertex, AC route is V2 vertex here both have origin A) … WebThe root node (19) will be our starting point. The right child weighs 3, whereas the left child weighs 2. 2. We must identify the broadest route. And 3 is currently the best option. Thus, the greedy algorithm will select 3. 3. Now, the weight of an only child of 3 is 1. This gives us our final outcome 19 + 3 + 1 = 23. greenwood ms post office hours
