Perhaps you should try some spelling variations:
"based computational and complexity from" » "and computational and complexity from" (Expand search), "by computational and complexity from" (Expand search), "based computational fluid complexity from" (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: (("based computational and complexity from") OR ("using codigo python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computational and complexity from\") OR (\"using codigo python python programming\"))*".
• Removing quotes may allow a broader search: (( based computational and complexity from ) OR ( using codigo python python programming ))*.
