Perhaps you should try some spelling variations:
"client modeling algorithm" » "client scheduling algorithm" (Expand Search), "agent modeling algorithm" (Expand Search), "event modeling algorithm" (Expand Search)
"element boosting algorithm" » "element cosine algorithm" (Expand Search)
"elements em algorithm" » "elements deer algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "elementi per 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 em algorithm") OR ((("client modeling algorithm") OR ("element boosting algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements em algorithm\") OR (((\"client modeling algorithm\") OR (\"element boosting algorithm\"))))".
• Removing quotes may allow a broader search: (( elements em algorithm ) OR ((( client modeling algorithm ) OR ( element boosting algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements em algorithm") OR ((("client modeling algorithm") OR ("element boosting algorithm"))))*.
