Perhaps you should try some spelling variations:
"elements presented algorithm" » "elements present algorithm" (Expand Search), "patients presented algorithm" (Expand Search), "elements related algorithm" (Expand Search)
"effect using algorithm" » "effect using algorithms" (Expand Search), "effect routing algorithm" (Expand Search), "effect fusion algorithm" (Expand Search), "effects using algorithm" (Expand Search), "effect size 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 presented algorithm") OR ("elements fe algorithm"))) OR ("effect using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements presented algorithm\") OR (\"elements fe algorithm\"))) OR (\"effect using algorithm\"))".
• Removing quotes may allow a broader search: (((( elements presented algorithm ) OR ( elements fe algorithm ))) OR ( effect using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements presented algorithm") OR ("elements fe algorithm"))) OR ("effect using algorithm"))*.
