Question
Which of the following branch and bound strategy leads to depth first search?Question 8Answera.Highest cost branch and boundb.FIFO branch and boundc.Lowest cost branch and boundd.LIFO branch and bound
Solution
The branch and bound strategy that leads to depth first search is d. LIFO (Last In, First Out) branch and bound.
Here's why:
-
In a depth-first search (DFS), you start at the root of the tree and explore as far as possible along each branch before backtracking. This means you go deep into a branch and then come back to explore the next branch.
-
A LIFO (Last In, First Out) strategy is one where the last node to be discovered is the first one to be expanded. This is exactly what happens in a depth-first search.
-
Therefore, a LIFO branch
