Perhaps you should try some spelling variations:
"_ computational code computer program" » "_ computational model computer program" (Expand search), "_ computational cost computer program" (Expand search), "_ computational models computer program" (Expand search), "_ computational node computer program" (Expand search), "_ computational one computer 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: (("_ computational code computer program") OR ("using modeling vpython python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"_ computational code computer program\") OR (\"using modeling vpython python programming\"))".
• Removing quotes may allow a broader search: (( _ computational code computer program ) OR ( using modeling vpython python programming )).
• Adding a wildcard symbol may retrieve word variants: (("_ computational code computer program") OR ("using modeling vpython python programming"))*.
