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