Perhaps you should try some spelling variations:
"and computational routines computer program" » "and computational routine computer program" (Expand search), "and computational solutions computer program" (Expand search), "and operational routines computer program" (Expand search), "_ computational routines computer program" (Expand search), "and computational routing computer program" (Expand search), "and computational routers computer 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: "((\"and computational routines computer program\") OR (\"using codigo python python programming\"))~".
• Removing quotes may allow a broader search: (( and computational routines computer program ) OR ( using codigo python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computational routines computer program") OR ("using codigo python python programming"))*.
