Perhaps you should try some spelling variations:
"using computational complexity computer program" » "using computational complexity complex program" (Expand search), "using computational complexity computacao program" (Expand search), "using computational complexity competences program" (Expand search)
"and computational of coding program" » "_ computational of coding program" (Expand search), "and computational one coding program" (Expand search), "and computational _ coding program" (Expand search), "and computational 3d coding program" (Expand search), "and computational of cloning program" (Expand search), "and computational of loading program" (Expand search), "and computational of cooling programs" (Expand search), "and computational non coding program" (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 computational of coding program") OR ("using computational complexity computer program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"and computational of coding program\") OR (\"using computational complexity computer program\"))*".
• Removing quotes may allow a broader search: (( and computational of coding program ) OR ( using computational complexity computer program ))*.
