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)
"element ree algorithm" » "element tree algorithms" (Expand Search), "element new algorithm" (Expand Search), "element rf algorithm" (Expand Search), "elements ree algorithm" (Expand Search), "elements res algorithm" (Expand Search), "element te 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 ("element ree algorithm"))) OR ("effect using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements presented algorithm\") OR (\"element ree algorithm\"))) OR (\"effect using algorithm\"))".
• Removing quotes may allow a broader search: (((( elements presented algorithm ) OR ( element ree algorithm ))) OR ( effect using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements presented algorithm") OR ("element ree algorithm"))) OR ("effect using algorithm"))*.
