Perhaps you should try some spelling variations:
"data processing algorithm" » "data modeling algorithm" (Expand Search), "data routing algorithm" (Expand Search), "data tracking algorithm" (Expand Search), "image processing algorithm" (Expand Search)
"select controls algorithm" » "select control algorithm" (Expand Search), "select control algorithms" (Expand Search), "select centrality algorithm" (Expand Search)
"element mesh algorithm" » "element best algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element means algorithm" (Expand Search), "element method algorithm" (Expand Search), "elements mges algorithm" (Expand Search), "element te 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 processing algorithm") OR ((("element mesh algorithm") OR ("select controls algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data processing algorithm\") OR (((\"element mesh algorithm\") OR (\"select controls algorithm\"))))".
• Removing quotes may allow a broader search: (( data processing algorithm ) OR ((( element mesh algorithm ) OR ( select controls algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data processing algorithm") OR ((("element mesh algorithm") OR ("select controls algorithm"))))*.
