Perhaps you should try some spelling variations:
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"order model algorithm" » "order novel algorithm" (Expand Search), "order modbo algorithm" (Expand Search), "order modeling algorithm" (Expand Search)
"element data algorithm" » "element data algorithms" (Expand Search), "element update algorithm" (Expand Search), "element atlas algorithm" (Expand Search), "settlement data algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement 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: (("order model algorithm") OR ((("element method algorithm") OR ("element data algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"order model algorithm\") OR (((\"element method algorithm\") OR (\"element data algorithm\"))))".
• Removing quotes may allow a broader search: (( order model algorithm ) OR ((( element method algorithm ) OR ( element data algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("order model algorithm") OR ((("element method algorithm") OR ("element data algorithm"))))*.
