Perhaps you should try some spelling variations:
"and computation in complex program" » "and computational in complex program" (Expand search), "of computation in complex program" (Expand search), "and computation in simplex program" (Expand search), "and computation in complex programmes" (Expand search), "and computation in complex prograded" (Expand search), "and computation and complex program" (Expand search), "and computation of complex program" (Expand search), "and imputation in 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"and computation in complex program\") OR (\"using code from python programming\"))~".
• Removing quotes may allow a broader search: (( and computation in complex program ) OR ( using code from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computation in complex program") OR ("using code from python programming"))*.
