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 coding pythons python programming" » "using codigo python python programming" (Expand search), "using coding methods python programming" (Expand search), "using coding python python programming" (Expand search), "using coding pitons python programming" (Expand search), "using coding piton python programming" (Expand search), "using coping pythons python programming" (Expand search), "using coating pythons python programming" (Expand search), "using cooking pythons 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: (("and computation in complex program") OR ("using coding pythons python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"and computation in complex program\") OR (\"using coding pythons python programming\"))".
• Removing quotes may allow a broader search: (( and computation in complex program ) OR ( using coding pythons python programming )).
• Adding a wildcard symbol may retrieve word variants: (("and computation in complex program") OR ("using coding pythons python programming"))*.
