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)
"complement rast algorithm" » "complement past algorithm" (Expand Search), "complement 5a algorithm" (Expand Search), "complement rim4 algorithm" (Expand Search), "complement best algorithm" (Expand Search), "complement forest algorithm" (Expand Search), "complement based 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 ("complement rast algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements control algorithm\") OR (\"complement rast algorithm\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( elements control algorithm ) OR ( complement rast algorithm ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements control algorithm") OR ("complement rast algorithm"))) OR ("level coding algorithm"))*.
