Evaluation and Assessment in Software Engineering
A cyber-cyber digital twin is a simulation of a software system. By contrast, a cyber-physical digital twin is a simulation of a nonsoftware (physical) system. Although cyber-physical digital twins have received a lot of recent attention, their cyber-cyber counterparts have been comparatively overlooked. In this paper we show how the unique properties of cyber-cyber digital twins open up exciting opportunities for research and development. Like all digital twins, the cyber-cyber digital twin isdoi:10.1145/3463274.3463275 fatcat:tx6bsam52jbofpxp5se34borni
