Perhaps you should try some spelling variations:
"using computation in complex program" » "using computational in complex program" (Expand search), "using imputation in complex program" (Expand search), "using compilation in complex program" (Expand search), "using computation in simplex program" (Expand search), "using computation in complex programmes" (Expand search), "using computation in complex prograded" (Expand search), "using computation and complex program" (Expand search), "using computation of complex program" (Expand search)
"using codigo python python programming" » "using codigo pythons python programming" (Expand search), "using codigo piton python programming" (Expand search), "using codigo pitons python programming" (Expand search), "using indigo python python programming" (Expand search), "using coding python python programming" (Expand search), "using codium python 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: "((\"using computation in complex program\") OR (\"using codigo python python programming\"))~".
• Removing quotes may allow a broader search: (( using computation in complex program ) OR ( using codigo python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computation in complex program") OR ("using codigo python python programming"))*.
