Perhaps you should try some spelling variations:
"complement component algorithm" » "complex components algorithm" (Expand Search)
"level coding algorithm" » "level cosine algorithm" (Expand Search), "level modeling algorithm" (Expand Search), "level finding algorithm" (Expand Search), "level according algorithm" (Expand Search), "level using algorithm" (Expand Search)
"elements b algorithm" » "elements _ algorithm" (Expand Search), "elements box algorithm" (Expand Search), "elements dbo algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element g 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 component algorithm") OR ("elements b algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"complement component algorithm\") OR (\"elements b algorithm\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( complement component algorithm ) OR ( elements b algorithm ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("complement component algorithm") OR ("elements b algorithm"))) OR ("level coding algorithm"))*.
