Perhaps you should try some spelling variations:
"by computational code complex program" » "by computational model complex program" (Expand search), "by computational cost complex program" (Expand search), "by computational models complex program" (Expand search), "_ computational code complex program" (Expand search), "and computational code complex program" (Expand search), "by computational code simplex program" (Expand search), "by computational code complex programmes" (Expand search), "by computational code complex prograded" (Expand search), "by computational core complex program" (Expand search), "by computational encode complex program" (Expand search), "by computational coffe complex 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: (("by computational code complex program") OR ("using code from python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"by computational code complex program\") OR (\"using code from python programming\"))".
• Removing quotes may allow a broader search: (( by computational code complex program ) OR ( using code from python programming )).
• Adding a wildcard symbol may retrieve word variants: (("by computational code complex program") OR ("using code from python programming"))*.
