Which data structure is primarily used by the Depth-First Search (DFS) algorithm?

  • AQueue
  • BHash Table
  • CStack
  • DHeap
Permalink
Correct Answer: Option C — Stack
Explanation: Depth-First Search (DFS) uses a stack to keep track of nodes during traversal. The algorithm explores one branch of a graph or tree as deeply as possible before backtracking to explore other branches. DFS can use an explicit stack or the system's call stack through recursion. This approach is useful for pathfinding, graph traversal, cycle detection, and topological sorting.

In Machine Learning, what is a hyperparameter?

  • AA configuration set before training
  • BA learned weight
  • CAn output label
  • DA type of dataset
Permalink
Correct Answer: Option A — A configuration set before training
Explanation: A hyperparameter is a setting or configuration chosen before training a machine learning model. Unlike model parameters, which are learned from data during training, hyperparameters are predefined by the user. Examples include the learning rate, batch size, number of epochs, and the number of hidden layers. Proper hyperparameter selection can significantly improve a model's accuracy and performance.

Which search algorithm explores all nodes one level at a time before moving to the next level?

  • AA* Search
  • BDepth-First Search (DFS)
  • CBreadth-First Search (BFS)
  • DGreedy Search
Permalink
Correct Answer: Option C — Breadth-First Search (BFS)
Explanation: Breadth-First Search (BFS) explores a graph or tree level by level, visiting all nodes at the current depth before moving to the next level. It uses a queue (FIFO) data structure to manage nodes. BFS is particularly useful for finding the shortest path in an unweighted graph because it guarantees the minimum number of edges from the starting node to the destination.
