Perhaps you should try some spelling variations:
"level coding algorithm" » "level cosine algorithm" (Expand Search), "level colony algorithm" (Expand Search), "level scheduling algorithm" (Expand Search)
"complementary cc3d algorithm" » "complementary rd algorithm" (Expand Search)
"element mesh algorithm" » "element deer algorithm" (Expand Search), "element search algorithm" (Expand Search), "elements mesh algorithm" (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: (((("complementary cc3d algorithm") OR ("element mesh algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"complementary cc3d algorithm\") OR (\"element mesh algorithm\"))) OR (\"level coding algorithm\"))*".
• Removing quotes may allow a broader search: (((( complementary cc3d algorithm ) OR ( element mesh algorithm ))) OR ( level coding algorithm ))*.
