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)
"effect testing algorithm" » "effect twisting algorithm" (Expand Search), "effect hastings algorithm" (Expand Search), "effect boosting algorithm" (Expand Search), "effect test algorithm" (Expand Search), "effect tests algorithm" (Expand Search), "effect using algorithm" (Expand Search)
"element mesh algorithm" » "element best algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element means algorithm" (Expand Search), "element method algorithm" (Expand Search), "elements mges 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 present algorithm") OR ("element mesh algorithm"))) OR ("effect testing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements present algorithm\") OR (\"element mesh algorithm\"))) OR (\"effect testing algorithm\"))".
• Removing quotes may allow a broader search: (((( elements present algorithm ) OR ( element mesh algorithm ))) OR ( effect testing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements present algorithm") OR ("element mesh algorithm"))) OR ("effect testing algorithm"))*.
