Perhaps you should try some spelling variations:
"element controls algorithm" » "element control algorithm" (Expand Search), "element control algorithms" (Expand Search), "element centrality algorithm" (Expand Search), "element contents algorithm" (Expand Search), "element content algorithm" (Expand Search), "select controls 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)
"complement mean algorithm" » "complement 5a algorithm" (Expand Search), "complement lectin algorithm" (Expand Search), "complements upon algorithm" (Expand Search), "complement means algorithm" (Expand Search), "complement new algorithm" (Expand Search), "complement each 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 mean algorithm") OR ("element controls algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"complement mean algorithm\") OR (\"element controls algorithm\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( complement mean algorithm ) OR ( element controls algorithm ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("complement mean algorithm") OR ("element controls algorithm"))) OR ("level coding algorithm"))*.
