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)
"based comparative in coding program" » "and comparative in coding program" (Expand search), "based collaborative in coding program" (Expand search), "revealed comparative in coding program" (Expand search), "based comparative and coding program" (Expand search), "based comparative in cloning program" (Expand search), "based comparative in loading program" (Expand search), "based comparative in cooling programs" (Expand search), "based comparative on coding program" (Expand search), "based comparative in decoding program" (Expand search), "based comparative 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: (("based comparative in coding program") OR ("using computational complexity computer program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based comparative in coding program\") OR (\"using computational complexity computer program\"))".
• Removing quotes may allow a broader search: (( based comparative in coding program ) OR ( using computational complexity computer program )).
• Adding a wildcard symbol may retrieve word variants: (("based comparative in coding program") OR ("using computational complexity computer program"))*.
