3. 3 CASs are a form of complex system

4. www.diversify-project.eu An essential property: diversity 4

5. www.diversify-project.eu Challenge Software in CAS for coordination to provide services to process information Current software engineering techniques require foresee all possible adaptation situations the system will have to face manually develop diverse solutions 5

6. www.diversify-project.eu DIVERSIFY brings together researchers from the domains of software-intensive distributed systems and ecology in order to translate ecological concepts and processes into software design principles 6

9. www.diversify-project.eu Objective DIVERSIFY aims at formalizing and experimenting new models and synthesis mechanisms for software diversity in collaborative adaptive systems, based on the ecological concept of biodiversity. The goal is to increase adaptive capacities in the face of structural and environmental variations. 9
