Perhaps you should try some spelling variations:
"elements cc3d algorithm" » "elements rd algorithm" (Expand Search)
"complement frog algorithms" » "implement frog algorithms" (Expand Search), "complementary frog algorithms" (Expand Search), "complement from algorithms" (Expand Search), "complement fog algorithms" (Expand Search)
"neural colony algorithm" » "neural colon algorithm" (Expand Search)

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("complement frog algorithms") OR ("elements cc3d algorithm"))) OR ("neural colony algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"complement frog algorithms\") OR (\"elements cc3d algorithm\"))) OR (\"neural colony algorithm\"))".
• Removing quotes may allow a broader search: (((( complement frog algorithms ) OR ( elements cc3d algorithm ))) OR ( neural colony algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("complement frog algorithms") OR ("elements cc3d algorithm"))) OR ("neural colony algorithm"))*.
