Perhaps you should try some spelling variations:
"effect tested algorithms" » "effect based algorithms" (Expand Search), "effect based algorithm" (Expand Search), "effect three algorithms" (Expand Search), "effect test algorithms" (Expand Search), "effect tests algorithms" (Expand Search), "effect testing algorithms" (Expand Search)
"element mining algorithm" » "element learning algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "element bonding algorithm" (Expand Search), "element modeling 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)

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

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