WebMar 21, 2024 · Greedy is an algorithmic paradigm that builds up a solution piece by piece, always choosing the next piece that offers the most obvious and immediate benefit. So the problems where choosing locally optimal also leads to global solution are the best fit for Greedy. For example consider the Fractional Knapsack Problem. WebMethod of Best First Search algorithm. Create two empty lists. Start from the inital node and add it to the ordered open list. Next the below steps are repeated until the final node or endpoint is reached. If the open list is empty exit the loop and return a False statement which says that the final node cannot be reached.
