Hybrid theory offers new way to model disturbed complex systems
Multi-scale complex systems are ubiquitous and also notoriously difficult to model. In disturbed systems, conventional bottom-up or top-down approaches can’t capture the interactions between the small-scale behaviors and the system-level properties. SFI External Professor John Harte and his collaborators have worked to resolve this challenge by building a hybrid method that links bottom-up behaviors and top-down causation in a single theory.
