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)
"elements mges algorithm" » "elements means algorithm" (Expand Search), "elements mogwo algorithm" (Expand Search), "elements magic algorithm" (Expand Search)
"elements ppm algorithm" » "elements ppo algorithm" (Expand Search), "elements pso algorithm" (Expand Search), "elements em algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "elements b algorithm" (Expand Search), "elements fe 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 ppm algorithm") OR ("elements mges algorithm"))) OR ("query processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements ppm algorithm\") OR (\"elements mges algorithm\"))) OR (\"query processing algorithm\"))".
• Removing quotes may allow a broader search: (((( elements ppm algorithm ) OR ( elements mges algorithm ))) OR ( query processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements ppm algorithm") OR ("elements mges algorithm"))) OR ("query processing algorithm"))*.
