Below, I'll go through some types of encryptions, share the leading encryption algorithms and explain why symmetric encryption remains a reliable method for secure data exchange. Data encryption ...

In the previous chapter, we already saw two approximation algorithms that started by solving a relaxation ... In this chapter, we will study such linear programming relaxations for Symmetric TSP with ...

Like in the asymmetric case (cf. Chapter 9), one can consider the generalization of Symmetric TSP where the start and end of the tour that we are looking for are not necessarily identical.
