Description

Session Goal: The session aimed to develop and optimize graph algorithms using Depth-First Search (DFS) techniques to determine network connectivity and identify critical connections or bridges.

Key Activities:

• Implemented two DFS algorithms to assess network connectivity and identify isolated nodes due to attacks, focusing on time complexity of O(|C|).
• Explored the identification of critical cables in a graph by recognizing bridges using DFS, enhancing efficiency by avoiding multiple DFS executions.
• Discussed the algorithmic process for bridge identification in graphs, emphasizing discovery and low values for backtracking cycle detection.
• Analyzed the complexity of the bridge identification algorithm, detailing the DFS operations and conditions for bridge detection.
• Optimized the amigos_debajo function using memoization to reduce redundant calculations and improve performance.
• Provided pseudocode for calculating nodes under a tree node in DFS, utilizing set operations for aggregation.

Achievements:

• Successfully developed efficient graph algorithms with DFS for network analysis.
• Improved algorithmic efficiency by adopting memoization techniques.

Pending Tasks:

• Further testing and validation of the optimized algorithms in real-world scenarios.
• Explore additional optimization techniques for large-scale graph data.
