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)
"element method algorithms" » "element two algorithms" (Expand Search), "element both algorithms" (Expand Search), "element other algorithms" (Expand Search)
"element ipca algorithm" » "element wgcna algorithm" (Expand Search), "element cscap algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element data 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 method algorithms") OR ("element ipca algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data processing algorithm\") OR (((\"element method algorithms\") OR (\"element ipca algorithm\"))))".
• Removing quotes may allow a broader search: (( data processing algorithm ) OR ((( element method algorithms ) OR ( element ipca algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data processing algorithm") OR ((("element method algorithms") OR ("element ipca algorithm"))))*.
