# Question: Which Is True Regarding BFS?

## Which of the following algorithm does not guaranteed to find a solution?

In decision tree learning, greedy algorithms are commonly used, however they are not guaranteed to find the optimal solution..

## What are the 3 types of heuristics?

In their initial research, Tversky and Kahneman proposed three heuristics—availability, representativeness, and anchoring and adjustment. Subsequent work has identified many more.

## What is an example of a heuristic?

Examples that employ heuristics include using trial and error, a rule of thumb or an educated guess.

## Is greedy search Complete?

In summary, greedy BFS is not complete, not optimal, has a time complexity of O(bm) and a space complexity which can be polynomial. A* is complete, optimal, and it has a time and space complexity of O(bm). So, in general, A* uses more memory than greedy BFS.

## Are heuristics good or bad?

Because heuristics simplify difficult decisions, they help us avoid “analysis paralysis” under conditions of uncertainty that demand speed. In that way, they can improve decision-making effectiveness. But they can also lead to mistakes.

## What is a heuristic function *?

A heuristic function, also called simply a heuristic, is a function that ranks alternatives in search algorithms at each branching step based on available information to decide which branch to follow. For example, it may approximate the exact solution.

## How do you identify greedy algorithm?

To make a greedy algorithm, identify an optimal substructure or subproblem in the problem. Then, determine what the solution will include (for example, the largest sum, the shortest path, etc.). Create some sort of iterative way to go through all of the subproblems and build a solution.

## What makes a good heuristic?

If you have a map with no obstacles and no slow terrain, then the shortest path from the starting point to the goal should be a straight line. If you’re using a simple heuristic (one which does not know about the obstacles on the map), it should match the exact heuristic.

## Is binary search a greedy algorithm?

I guess if you squint at it sideways, binary search is greedy in the sense that you’re trying to cut down your search space by as much as you can in each step. It just happens to be a greedy algorithm in a search space with structure making that both efficient, and always likely to find the right answer.

## Which search is implemented with first in first out queue?

In breadth-first search the frontier is implemented as a FIFO (first-in, first-out) queue.

## What are the two types of heuristic?

Heuristics come in all flavors, but two main types are the representativeness heuristic and the availability heuristic.

heuristic functionWhat is the other name of informed search strategy? Explanation: A key point of informed search strategy is heuristic function, So it is called as heuristic function.

## Who is the father of artificial intelligence?

John McCarthyIn 1955, John McCarthy coined the term Artificial Intelligence, which he proposed in the famous Dartmouth conference in 1956. This conference attended by 10-computer scientists, saw McCarthy explore ways in which machines can learn and reason like humans.

## Which of the following is not an application of AI?

Explanation: Content mining is not an application of AI.

## What is another word for heuristic?

Synonyms forinterested.interrogative.probing.prying.questioning.searching.analytical.doubtful.

## What is heuristic behavior?

Heuristics are commonly defined as cognitive shortcuts or rules of thumb that simplify decisions, especially under conditions of uncertainty. They represent a process of substituting a difficult question with an easier one (Kahneman, 2003). Heuristics can also lead to cognitive biases.

## How do we use heuristics in everyday life?

“Contagion heuristic” causes an individual to avoid something that is thought to be bad or contaminated. For example, when eggs are recalled due to a salmonella outbreak, someone might apply this simple solution and decide to avoid eggs altogether to prevent sickness.
