Perhaps you should try some spelling variations:
"query processing algorithm" » "query modeling algorithm" (Expand Search), "query routing algorithm" (Expand Search), "query tracking algorithm" (Expand Search), "pre processing algorithm" (Expand Search)
"effect tests algorithms" » "effect tested algorithms" (Expand Search), "effect best algorithms" (Expand Search), "effect best algorithm" (Expand Search), "effect test algorithms" (Expand Search), "effect results algorithms" (Expand Search), "exact tests algorithms" (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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"query processing algorithm\") OR (\"element mesh algorithm\"))) OR (\"effect tests algorithms\"))~".
• Removing quotes may allow a broader search: (((( query processing algorithm ) OR ( element mesh algorithm ))) OR ( effect tests algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("query processing algorithm") OR ("element mesh algorithm"))) OR ("effect tests algorithms"))*.
