Complexity Explorer

Courses offer the chance to delve deeply into a particular topic and culminate in a certificate of completion for participants who earn passing marks. Courses are accompanied by un-graded quizzes for self-assessment as well as graded exams at the end of each module. TAs are available to answer questions or provide clarifications.

Tutorials offer a focused overview of particular techniques or tools and examples of how they can be applied to complex systems.

Most courses and tutorials are available asynchronously on demand and can be completed at your own pace.

Complexity Explorer is supported by user donations and contributions from the Santa Fe Institute. Please consider donating to support new content development.
