Perhaps you should try some spelling variations:
"elements control algorithm" » "element controls algorithm" (Expand Search), "helminths control algorithm" (Expand Search), "element content 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 fe algorithm" » "elements new algorithm" (Expand Search), "elements de algorithms" (Expand Search), "elements seu algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "element te algorithm" (Expand Search), "elements b 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: (((("elements control algorithm") OR ("elements fe algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements control algorithm\") OR (\"elements fe algorithm\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( elements control algorithm ) OR ( elements fe algorithm ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements control algorithm") OR ("elements fe algorithm"))) OR ("level coding algorithm"))*.
