Perhaps you should try some spelling variations:
"dependent processing algorithm" » "dependent processes algorithm" (Expand Search), "dependent protein algorithm" (Expand Search), "dependent properties algorithm" (Expand Search)
"elements pso algorithm" » "elements two algorithms" (Expand Search), "elements _ algorithm" (Expand Search), "elements new algorithm" (Expand Search), "elements ppm algorithm" (Expand Search), "elements upon algorithm" (Expand Search)
"elements em algorithm" » "elements new algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "elements _ algorithms" (Expand Search), "elements ree algorithm" (Expand Search), "elements ppm algorithm" (Expand Search), "elements res algorithm" (Expand Search)

Try widening your search to All Fields.

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

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