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 control algorithm" » "element controls algorithm" (Expand Search), "element content algorithm" (Expand Search), "dependent control 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: (((("host clustering algorithm") OR ("data modeling algorithm"))) OR ("element control algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"host clustering algorithm\") OR (\"data modeling algorithm\"))) OR (\"element control algorithm\"))".
• Removing quotes may allow a broader search: (((( host clustering algorithm ) OR ( data modeling algorithm ))) OR ( element control algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("host clustering algorithm") OR ("data modeling algorithm"))) OR ("element control algorithm"))*.
