Perhaps you should try some spelling variations:
"based computational simulation computer program" » "and computational simulation computer program" (Expand search), "by computational simulation computer program" (Expand search), "based computational simulation computers program" (Expand search)
"using code from python programming" » "using code from pathogen programming" (Expand search), "using code from anthony programming" (Expand search), "using cone from python programming" (Expand search), "using co from python programming" (Expand search), "using co2 from python programming" (Expand search), "using code form 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 computational simulation computer program") OR ("using code from python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computational simulation computer program\") OR (\"using code from python programming\"))".
• Removing quotes may allow a broader search: (( based computational simulation computer program ) OR ( using code from python programming )).
• Adding a wildcard symbol may retrieve word variants: (("based computational simulation computer program") OR ("using code from python programming"))*.
