- “SimCity: In response, Facebook built a scaled-down version of its platform to simulate user behavior. Called WW, it helps engineers identify and fix the undesired consequences of new updates before they’re deployed.
- Bot doppelgangers: Facebook simulates hundreds to thousands of its users at a time with a mix of hard-coded and machine-learning-based bots.
- Automatic design: While the scenarios play out, the system automatically adjusts different parameters in the simulation, such as the bots’ privacy settings or the constraints on their actions.
- Hidden from view: In order to create as realistic a simulation as possible, WW is actually built directly on the live platform rather than a separate testing version”
