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), "elements method algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion algorithm" (Expand Search)
"scale model algorithm" » "scale novel algorithm" (Expand Search), "scale modbo algorithm" (Expand Search), "scale modeling algorithm" (Expand Search), "simple model 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 ((("data using algorithm") OR ("scale model algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"data using algorithm\") OR (\"scale model algorithm\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( data using algorithm ) OR ( scale model algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("data using algorithm") OR ("scale model algorithm"))))*.
