Perhaps you should try some spelling variations:
"using computational complexity computer program" » "and computational complexity computer program" (Expand search), "using computational complexity complex program" (Expand search), "using computational complexity computacao program" (Expand search), "using computational complexity competences program" (Expand search)
"code application and coding program" » "code applications and coding program" (Expand search), "core application and coding program" (Expand search), "case application and coding program" (Expand search), "code application _ coding program" (Expand search), "code application and cloning program" (Expand search), "code application and loading program" (Expand search), "code application and cooling programs" (Expand search), "code application and coping program" (Expand search), "code application and cooling program" (Expand search), "code application and cooking 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: (("code application and coding program") OR ("using computational complexity computer program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"code application and coding program\") OR (\"using computational complexity computer program\"))".
• Removing quotes may allow a broader search: (( code application and coding program ) OR ( using computational complexity computer program )).
• Adding a wildcard symbol may retrieve word variants: (("code application and coding program") OR ("using computational complexity computer program"))*.
