Perhaps you should try some spelling variations:
"based computation using active program" » "based computational using active program" (Expand search), "based competition using active program" (Expand search), "based compilation using active program" (Expand search), "based computations using active program" (Expand search), "based computation in active program" (Expand search), "based composition using active program" (Expand search), "based computation using action program" (Expand search), "based computation using activity program" (Expand search), "based computation using practice program" (Expand search)
"using modeling vpython python programming" » "using modeling method python programming" (Expand search), "using model vpython python programming" (Expand search), "using modern vpython python programming" (Expand search), "using models vpython python programming" (Expand search), "using modeling python python programming" (Expand search), "using modeling pythons python programming" (Expand search), "using modeling piton python programming" (Expand search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("based computation using active program") OR ("using modeling vpython python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computation using active program\") OR (\"using modeling vpython python programming\"))".
• Removing quotes may allow a broader search: (( based computation using active program ) OR ( using modeling vpython python programming )).
• Adding a wildcard symbol may retrieve word variants: (("based computation using active program") OR ("using modeling vpython python programming"))*.
