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