  2. Types of Resources • Standalone systems (high level) • Agents: AgentSheets, NetLogo • Mathematical: MatLab, Mathematica • Software frameworks • Java: Ascape, MASON, RePast • Objective C: Swarm • Programming languages • C/C++ • Java

  3. Code words • Speed of execution: • Interpreted => slow • Compiled => faster • Java: object-oriented language • Signifies multi-platform capability (Windows, Mac, Unix/Linux, other) • signifies free availability • Cost: nominal: < $100; moderate: <$1000; else expensive

  4. AgentSheets • Simplest agent modeling system • Programming: it’s own visual language, interpreted • Main use: educational tool, including kids • Availability: multi-platform, Java compiler (applets), nominal cost

  5. NetLogo • Simplest agent modeling system useful to researchers • Programming: it’s own object-oriented agent language, interpreted, new 3D visuals • Main use: education + research • Availability: multi-platform, written in Java, applets, free

  6. MatLab • Highly capable numerical analysis engine and modeling system • Programming: it’s own language, object-oriented extensions, compiled • Main use: scientists and engineers; can be used for agent models • Availability: multi-platform, moderate cost, need MatLab engine to run, good support, large user group

  7. Mathematica • Canonical system for doing symbolic mathematics • Programming: it’s own interpreted language, partially compiled; weak object-oriented extensions; compact • Main use: scientists and engineers; sometimes used for agent models • Availability: multi-platform, expensive, need Mathematica to run

  8. Swarm • Early agent modeling system, written by C. Langton at Santa Fe • Programming: Objective C (semi-archaic); difficult to install; Unix/Linux only • Main use: many early agent models • Availability: free, open source at Swarm.org

  9. Ascape • First agent modeling framework aimed at social scientists • Programming: Java • Main use: Spatial social science models (e.g., Sugarscape, Anasazi) • Availability: multi-platform,applets, version 1.9 free, open source; version 3.0 commercial

  10. RePast->SimPhony • Agent modeling platform targeted at social scientists • Programming: Java and .Net C# -> visual language; new extensions to GIS systems (GRASS) • Main use: social science • Availability: multi-platforms,applets,free, open source, large user group, good support

  11. MASON • Next generation agent modeling system for social scientists and others • Programming: Java • Main use: social and computer science; separates simulation engine, visualization and analysis • Availability: multi-platform,applets,free and open source, good support

  12. Java • Canonical object-oriented multi-platform programming environment • Programming: compiled to machine independent form, pretty fast; social scientists need 1 course to do it well • Main use: widely used in all fields • Availability: multi-platform,applets, free, including many good IDEs

  13. C/C++ • Canonical object-oriented programming environment • Programming: compiled to machine specific form, fastest execution time; social scientists need 1 course to do it safely, often 1 more to do it well • Main use: widely used in all fields • Availability: code can be multi-platform, binaries not multi-platform, free to expensive
