Perhaps you should try some spelling variations:
"data modeling algorithm" » "data making algorithm" (Expand Search), "data modelling algorithm" (Expand Search), "data models algorithm" (Expand Search)
"host clustering algorithm" » "high clustering algorithm" (Expand Search), "based clustering algorithm" (Expand Search), "local clustering algorithm" (Expand Search)
"element based algorithm" » "engagement based 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: (("element based algorithm") OR ((("data modeling algorithm") OR ("host clustering algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element based algorithm\") OR (((\"data modeling algorithm\") OR (\"host clustering algorithm\"))))".
• Removing quotes may allow a broader search: (( element based algorithm ) OR ((( data modeling algorithm ) OR ( host clustering algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element based algorithm") OR ((("data modeling algorithm") OR ("host clustering algorithm"))))*.
