This book constitutes the refereed post-conference proceedings of the Special Event on the Analysis of Experimental Algorithms, SEA(2) 2019, held in Kalamata, Greece, in June 2019.

The 35 revised full papers presented were carefully reviewed and selected from 45 submissions. The papers cover a wide range of topics in both computer science and operations research/mathematical programming. They focus on the role of experimentation and engineering techniques in the design and evaluation of algorithms, data structures, and computational optimization methods.
