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  Math based  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

• f the model?

 Agent-based computational modeling

Slide 6 Fall 201 2015

 Integrated programming,

simulation and visualization environment

 Library of models in

many different fields

 Useful to us as an object

• f study

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
