Perhaps you should try some spelling variations:
"element controls algorithm" » "element control algorithm" (Expand Search), "element control algorithms" (Expand Search), "element centrality algorithm" (Expand Search), "element contents algorithm" (Expand Search), "element content algorithm" (Expand Search), "select controls algorithm" (Expand Search)
"data modeling algorithm" » "data making algorithm" (Expand Search), "data modelling algorithm" (Expand Search), "data models algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean 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 controls algorithm") OR ("element method algorithm"))) OR ("data modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element controls algorithm\") OR (\"element method algorithm\"))) OR (\"data modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( element controls algorithm ) OR ( element method algorithm ))) OR ( data modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element controls algorithm") OR ("element method algorithm"))) OR ("data modeling algorithm"))*.
