Perhaps you should try some spelling variations:
"field modeling algorithm" » "field making algorithm" (Expand Search), "field model algorithm" (Expand Search), "unified modeling algorithm" (Expand Search)
"element methods algorithm" » "element means algorithm" (Expand Search), "element network algorithm" (Expand Search), "treatment methods algorithm" (Expand Search), "dependent methods 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 method algorithm") OR ((("field modeling algorithm") OR ("element methods algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"field modeling algorithm\") OR (\"element methods algorithm\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( field modeling algorithm ) OR ( element methods algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("field modeling algorithm") OR ("element methods algorithm"))))*.
