Computational Modeling CT @ VT Computational Modeling The third - PowerPoint PPT Presentation

Introduction to Computational Thinking Computational Modeling

CT @ VT Computational Modeling  The “third pillar” of science and engineering  Lab based Science and Engineering  Math based computational experimental theoretical  Computer based  Advantages  Reduce risky experiments study drug behavior in the body   Reduce cost for discovery can run millions of virtual experiments   Explore ill-understood phenomenon Emergent behavior (see more in a minute)   Cautions  Validation: is the model an accurate representation of reality ?  Verification: is the computation an accurate representation of the model?

CT @ VT NetLogo  Agent-based computational modeling  Integrated programming, simulation and visualization environment  Library of models in many different fields  Useful to us as an object of study Fall 201 2015 Slide 6

CT @ VT Cohort work  Each cohort will be given the name of a NetLogo model  Answer in-class questions related to this NetLogo model  Report back 20 minutes before end of class Fall 201 2015 Slide 7
