WebJul 6, 2024 · The relaxation is a powerful technique to design approximation algorithms. It is similar to restriction, in terms of making a change on feasible domain; however, in an opposite direction, i.e., instead of shrinking the feasible domain, enlarge it by relaxing certain constraint. There are various issues about relaxation.
