Perhaps you should try some spelling variations:
"using computational complexity complex program" » "and computational complexity complex program" (Expand search), "using computational complexity simplex program" (Expand search), "using computational complexity complex programmes" (Expand search), "using computational complexity complex prograded" (Expand search)
"code complexation in coding program" » "code completion in coding program" (Expand search), "co2 complexation in coding program" (Expand search), "copper complexation in coding program" (Expand search), "code complexation and coding program" (Expand search), "code complexation of coding program" (Expand search), "code complication in coding program" (Expand search), "code complexation in cloning program" (Expand search), "code complexation in loading program" (Expand search), "code complexation in cooling programs" (Expand search), "code complexation on coding program" (Expand search), "code complexation in decoding program" (Expand search), "code complexation 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: (("code complexation in coding program") OR ("using computational complexity complex program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"code complexation in coding program\") OR (\"using computational complexity complex program\"))".
• Removing quotes may allow a broader search: (( code complexation in coding program ) OR ( using computational complexity complex program )).
• Adding a wildcard symbol may retrieve word variants: (("code complexation in coding program") OR ("using computational complexity complex program"))*.
