Perhaps you should try some spelling variations:
"_ computational code computational program" » "_ computational model computational program" (Expand search), "_ computational cost computational program" (Expand search), "_ computational models computational program" (Expand search), "_ computational cfd computational program" (Expand search), "_ computational some computational 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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("_ computational code computational program") OR ("using codigo python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"_ computational code computational program\") OR (\"using codigo python python programming\"))".
• Removing quotes may allow a broader search: (( _ computational code computational program ) OR ( using codigo python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("_ computational code computational program") OR ("using codigo python python programming"))*.
