🧠 AI Search Algorithms Interview Questions with Answers (Part 1)
1️⃣ What is a Search Algorithm in AI?
👉 A Search Algorithm is a method used by an AI system to explore possible states or actions to find a solution to a problem.
📌 Basic process:
Initial State → Possible Actions → Search → Goal State
Examples:
🔹 Route Finding 🗺
🔹 Game Playing 🎮
🔹 Puzzle Solving 🧩
🔹 Planning 🤖
2️⃣ What is Breadth-First Search (BFS)?
👉 BFS explores nodes level by level, starting from the initial node.
Example:

        A
       / \
      B   C
     / \
    D   E

BFS Order:

A → B → C → D → E

💡 BFS typically uses a Queue.
⏱️ Time Complexity: O(V + E)
💾 Space Complexity: O(V)
3️⃣ What is Depth-First Search (DFS)?
👉 DFS explores a path as deeply as possible before backtracking.
Example:

        A
       / \
      B   C
     / \
    D   E

One possible DFS Order:

A → B → D → E → C

💡 DFS can be implemented using recursion or a stack.
⏱️ Time Complexity: O(V + E)
💾 Space Complexity: O(V)
4️⃣ What is A (A-Star) Search Algorithm?*
👉 A* is a heuristic search algorithm that uses both the cost already traveled and an estimate of the remaining cost to choose which node to explore.
It uses:

f(n) = g(n) + h(n)

🔹 g(n) → Cost from the start to node n
🔹 h(n) → Estimated cost from n to the goal
🔹 f(n) → Estimated total cost
Applications:
🗺 Pathfinding
🎮 Game AI
🤖 Robot Navigation
5️⃣ What is a Heuristic Function in AI?
👉 A heuristic function estimates how close a current state is to the goal.
It is commonly represented as:

h(n)

Example:
In a map-navigation problem, the straight-line distance to the destination can be used as a heuristic for some pathfinding problems.
💡 A good heuristic can reduce the amount of search required, but its properties affect whether an algorithm can guarantee an optimal solution.

🧠 AI Search Algorithms Interview Questions with Answers (Part 2)
6️⃣ What is Greedy Best-First Search?
👉 Greedy Best-First Search selects the node that appears closest to the goal based on a heuristic function.
It uses:

f(n) = h(n)

🔹 h(n) → Estimated cost from the current node to the goal
💡 Unlike A*, it does not include the cost already traveled.
⏱️ Time Complexity: Depends on the search space
💾 Space Complexity: Can be large
7️⃣ What is Hill Climbing in AI?
👉 Hill Climbing is a local search algorithm that repeatedly moves to a neighboring state that improves the objective value.
📌 Basic process:

Current State
     ↓
Check Neighbors
     ↓
Choose Better State
     ↓
Repeat

Common problems:
🔹 Local Maximum
🔹 Plateau
🔹 Ridge
💡 Hill climbing does not always guarantee finding the global optimum.
8️⃣ What is the Minimax Algorithm?
👉 Minimax is a decision-making algorithm commonly used in two-player, turn-based games.
One player tries to maximize the score, while the opponent tries to minimize it.
Example:

             MAX
           /     \
        MIN       MIN
       /  \      /  \
      3    5    2    9

The algorithm evaluates possible game states and chooses a move based on the assumed optimal play of both sides.
🎮 Commonly associated with:
• Chess
• Tic-Tac-Toe
• Checkers
9️⃣ What is Alpha-Beta Pruning?
👉 Alpha-Beta Pruning is an optimization of Minimax that eliminates branches that cannot affect the final decision.
It uses two values:
🔹 Alpha (α) → Best value found so far for the maximizing player
🔹 Beta (β) → Best value found so far for the minimizing player
📌 When:

α ≥ β

the remaining branch can be pruned.
💡 It can reduce the number of game-tree nodes that need to be evaluated while producing the same Minimax result.
🔟 What is Game AI?
👉 Game AI refers to techniques used to create systems that allow non-player characters (NPCs) or game agents to make decisions and respond to game situations.
Common techniques include:
🔹 Minimax
🔹 Alpha-Beta Pruning
🔹 Pathfinding
🔹 Finite State Machines
🔹 Behavior Trees
🔹 A* Search
Example:
🎮 An enemy NPC can use pathfinding to navigate toward a player while avoiding obstacles.

🚀 Generative AI Interview Questions with Answers (Part 7)
3️⃣1️⃣ What is LLM Architecture?
👉 LLM architecture refers to the design and components used to build a Large Language Model. Modern LLMs commonly use Transformer-based architectures.
📌 Basic flow:

Input Text
    ↓
Tokenization
    ↓
Token Embeddings
    ↓
Transformer Layers
    ↓
Output Probabilities
    ↓
Generated Text

💡 The exact architecture can differ between models.
3️⃣2️⃣ What is Self-Attention?
👉 Self-Attention allows a model to determine which tokens in an input are most relevant to each other while processing a sequence.
Example:

"The animal didn't cross the road because it was tired."

Attention helps the model consider relationships between words across the sentence.
📌 Self-Attention is a core component of Transformer architectures.
3️⃣3️⃣ What is the Difference Between Encoder and Decoder in Transformers?
👉 Encoder and Decoder are two major Transformer components.
🔹 Encoder → Primarily processes input and builds contextual representations.
🔹 Decoder → Generates output tokens, often using previously generated tokens as context.
Examples:

Encoder → Understanding / Representation
Decoder → Text Generation

💡 Some models use encoder-only architectures, some decoder-only, and some use both.
3️⃣4️⃣ What is Pretraining in LLMs?
👉 Pretraining is the initial large-scale training stage where an LLM learns general language patterns, relationships, and representations from a large dataset.
📌 Basic process:

Large Dataset
      ↓
Tokenization
      ↓
Model Training
      ↓
Learned Parameters
      ↓
Pretrained Model

💡 Pretraining provides the foundation that can later be adapted for specific applications.
3️⃣5️⃣ What is Inference in an LLM?
👉 LLM inference is the process of using a trained model to generate an output for a given input.
Example:

User Prompt
    ↓
Tokenization
    ↓
LLM
    ↓
Next-Token Prediction
    ↓
Generated Response

💡 During inference, the model uses its learned parameters to generate output rather than learning new parameters.

🚀 Generative AI Interview Questions with Answers (Part 9)
4️⃣1️⃣ What are Query, Key, and Value (Q, K, V) in Attention?
👉 In the attention mechanism, each token is transformed into three vectors:
🔹 Query (Q) → What information am I looking for?
🔹 Key (K) → What information do I contain?
🔹 Value (V) → What information should I provide?
A simplified attention calculation is:

Attention(Q, K, V)
= softmax(QKᵀ / √dₖ)V

💡 Q, K, and V help the model determine which tokens should receive more attention.
4️⃣2️⃣ What are Logits in an LLM?
👉 Logits are the raw numerical scores produced by a model before they are converted into probabilities.
📌 Simplified flow:

Input
 ↓
LLM
 ↓
Logits
 ↓
Softmax
 ↓
Probabilities
 ↓
Next Token

💡 Higher relative logits generally correspond to higher probabilities after softmax.
4️⃣3️⃣ What is Softmax in AI?
👉 Softmax converts a set of numerical scores into a probability distribution.
For example:

Logits
 ↓
Softmax
 ↓
Token A → 0.70
Token B → 0.20
Token C → 0.10

📌 The probabilities sum to approximately 1.
💡 Softmax is commonly used for converting model scores into probabilities over possible classes or tokens.
4️⃣4️⃣ What is Greedy Decoding?
👉 Greedy decoding selects the highest-probability token at each generation step.
Example:

Token probabilities

A → 0.70
B → 0.20
C → 0.10

Selected → A

📌 It is simple and deterministic for a fixed model/input, but it may not always produce the most desirable overall sequence.
4️⃣5️⃣ What is Sampling in Generative AI?
👉 Sampling selects the next token probabilistically from a distribution rather than always choosing the highest-probability token.
Common decoding controls include:
🔹 Temperature
🔹 Top-P
🔹 Top-K
📌 Sampling can produce more varied outputs than greedy decoding.
💡 The exact behavior depends on the model and decoding settings.
