Perhaps you should try some spelling variations:
"elements present algorithm" » "elements presented algorithm" (Expand Search), "elements treatment algorithm" (Expand Search), "elements forest algorithm" (Expand Search)
"elements means algorithm" » "elements search algorithm" (Expand Search), "elements mges algorithm" (Expand Search), "elements res 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)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("elements present algorithm") OR ("elements means algorithm"))) OR ("effect using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements present algorithm\") OR (\"elements means algorithm\"))) OR (\"effect using algorithm\"))".
• Removing quotes may allow a broader search: (((( elements present algorithm ) OR ( elements means algorithm ))) OR ( effect using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements present algorithm") OR ("elements means algorithm"))) OR ("effect using algorithm"))*.
