mcq 队列

1) The main Aim of the AI system is to provide a solution for real-life problems by acting and thinking humanly. Whenever an agent is confronted by a problem, what is the first step that it follows towards searching a solution to the problem?

1. Searching for relevant data in the surroundings

2. Searching into its own knowledge base for solutions

3. Seeking for human inputs for approaching towards the solution

4. None of the above

Answer & Explanation

Correct answer: 2
Searching into its own knowledge base for solutions

Whenever an AI-based agent is confronted by a problem, it first looks into its database for a solution or similar type of problem. Then it looks at other places like perceiving the environment, applying logic, etc.

1)AI系统的主要目的是通过人为行动和思考为现实生活中的问题提供解决方案。 每当代理人遇到问题时，朝着寻求解决方案的第一步是什么？

1. 搜索周围的相关数据

2. 搜索自己的知识库以寻求解决方案

3. 寻求人力资源以寻求解决方案

4. 以上都不是

答案与解释

正确答案：2
搜索自己的知识库以寻求解决方案

每当基于AI的代理遇到问题时，它都会首先在其数据库中查找解决方案或类似类型的问题。 然后，它着眼于其他地方，例如感知环境，应用逻辑等。

2) Which of the following mentioned searches are heuristic searches?

1. Random Search

2. Depth First Search

3. Breadth First Search

4. Best First Search

Options:

1. Only iv.

2. All i., ii., iii. and iv.

3. ii. and iv.

4. None of the above

Answer & Explanation

Correct answer: 1
Only iv.

In the best first search, which is also known as the heuristic search, the agent picks up the best node based upon the heuristic value irrespective of where the node is.

2)以下提到的哪些搜索是启发式搜索？

1. 随机搜寻

2. 深度优先搜索

3. 广度优先搜索

4. 最佳优先搜索

选项：

1. 只有iv。

2. 全部i。，ii。，iii。 iv。

3. ii。 iv。

4. 以上都不是

答案与解释

正确答案：1
只有iv。

在最佳的第一搜索(也称为启发式搜索)中，代理基于启发式值选择最佳节点，而与节点的位置无关。

3) Which of the mentioned properties of heuristic search differentiates it from other searches?

1. It provides solution in a reasonable time frame

2. It provides the reasonably accurate direction to a goal

3. It considers both actual costs that it took to reach the current state and approximate cost it would take to reach the goal from the current state

4. All of the above

Answer & Explanation

Correct answer: 4
All of the above

All the mentioned options are the properties that differentiate a heuristic search from other searches.

3)启发式搜索中提到的哪些属性与其他搜索有区别？

1. 它在合理的时间内提供解决方案

2. 它为目标提供了合理准确的方向

3. 它既考虑了达到当前状态所需的实际成本，也考虑了从当前状态达到目标所需的近似成本

4. 上述所有的

答案与解释

正确答案：4
上述所有的

所有提到的选项都是将启发式搜索与其他搜索区分开的属性。

4) Consider the following statement:
\”The search first begins from the root node and the first one of the child node’s sub-tree is completely traversed. That is, first all the one-sided nodes are checked, and then the other sided nodes are checked.\”
Which search algorithm is described in the above definition?

1. The Breadth First Search (BFS)

2. The Depth First Search (DFS)

3. The A* search

4. None of the above

Answer & Explanation

Correct answer: 2
The Depth First Search (DFS)

In DFS, the search first begins from the root node and the first one of the child node’s sub-tree is completely traversed. That is, first all the one-sided nodes are checked, and then the other sided nodes are checked.

4)考虑以下陈述：
“搜索首先从根节点开始，子节点的子树中的第一个子树被完全遍历。也就是说，首先检查所有单侧节点，然后再检查另一侧节点。”
上面的定义描述了哪种搜索算法？

1. 广度优先搜索(BFS)

2. 深度优先搜索(DFS)

3. A *搜索

4. 以上都不是

答案与解释

正确答案：2
深度优先搜索(DFS)

在DFS中，搜索首先从根节点开始，子节点的子树中的第一个子树被完全遍历。 即，首先检查所有单侧节点，然后检查另一侧节点。

5) Consider the following statement:
\”In AI search algorithms, we look for a solution which provides us the most optimized way in terms of both time and cost to reach from the current state to the Goal State.\”
State whether the above condition is true or false?

1. True

2. False

Answer & Explanation

Correct answer: 1
True

If we want to optimize our algorithm, we must take care of both the time limit as well as the cost that occurred in our searching. The lesser they are, the more efficient our algorithm is.

5)考虑以下语句：
“在AI搜索算法中，我们正在寻找一种解决方案，该解决方案可为我们提供从当前状态到目标状态的时间和成本方面最优化的方式。”
说明上述条件是对还是错？

1. 真正

2. 假

答案与解释

正确答案：1
真正

如果要优化算法，则必须考虑时间限制以及搜索中发生的成本。 它们越小，我们的算法就越有效。
