Perhaps you should try some spelling variations:
modeling vpython » modeling method (Expand search)
some complexity » sme complexity (Expand search), code complexity (Expand search), time complexity (Expand search)
using modeling » using model (Expand search), using modern (Expand search), using models (Expand search)
vpython python » python python (Expand search), pythons python (Expand search), piton python (Expand search)
coder some » code some (Expand search), border some (Expand search), over some (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( coder some complexity control program ) OR ( using modeling vpython python programming ))~.
