Approximation Algorithms

Explore approximation algorithms in this 41-minute ACM conference talk. Dive into the Connectivity Augmentation Problem and its reduction to Steiner Tree. Examine lower bounds and approximation algorithms using linear programming. Investigate spectral network design, including generalized survivable networks and spectral rounding. Learn about main results, spectral certificates, and future work in the field. Conclude with insights into conjunctive normal form (CNF) and classic Glauber dynamics Gibbs sampling.
