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)
"complement pass algorithm" » "complement jaya algorithm" (Expand Search), "implement pass algorithm" (Expand Search), "complementary pass algorithm" (Expand Search)
"element update algorithm" » "elements update algorithm" (Expand Search), "element updated algorithm" (Expand Search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"complement pass algorithm\") OR (\"element update algorithm\"))) OR (\"level coding algorithm\"))~".
• Removing quotes may allow a broader search: (((( complement pass algorithm ) OR ( element update algorithm ))) OR ( level coding algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("complement pass algorithm") OR ("element update algorithm"))) OR ("level coding algorithm"))*.
