Perhaps you should try some spelling variations:
"element controls algorithm" » "element control algorithm" (Expand Search), "elements controls algorithm" (Expand Search)
"level coding algorithm" » "level cosine algorithm" (Expand Search), "level colony algorithm" (Expand Search), "level scheduling algorithm" (Expand Search)
"complement coa algorithm" » "complement jaya algorithm" (Expand Search), "complement rd algorithm" (Expand Search), "complement colony algorithm" (Expand Search), "implement coa algorithm" (Expand Search), "complementary coa 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 coa algorithm\") OR (\"element controls algorithm\"))) OR (\"level coding algorithm\"))~".
• Removing quotes may allow a broader search: (((( complement coa algorithm ) OR ( element controls algorithm ))) OR ( level coding algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("complement coa algorithm") OR ("element controls algorithm"))) OR ("level coding algorithm"))*.
