Perhaps you should try some spelling variations:
"movement tracking algorithm" » "movement learning algorithm" (Expand Search), "movement processing algorithm" (Expand Search)
"client mining algorithm" » "client learning algorithm" (Expand Search), "client means algorithm" (Expand Search)
"element swarm algorithm" » "element search algorithm" (Expand Search), "element software 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: (((("movement tracking algorithm") OR ("element swarm algorithm"))) OR ("client mining algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"movement tracking algorithm\") OR (\"element swarm algorithm\"))) OR (\"client mining algorithm\"))".
• Removing quotes may allow a broader search: (((( movement tracking algorithm ) OR ( element swarm algorithm ))) OR ( client mining algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("movement tracking algorithm") OR ("element swarm algorithm"))) OR ("client mining algorithm"))*.
