Perhaps you should try some spelling variations:
"scale modeling algorithm" » "scale scheduling algorithm" (Expand Search)
"element custom algorithm" » "element control algorithm" (Expand Search), "element auction algorithm" (Expand Search), "element cosine algorithm" (Expand Search), "elements custom algorithm" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method 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: (("scale modeling algorithm") OR ((("element custom algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"scale modeling algorithm\") OR (((\"element custom algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( scale modeling algorithm ) OR ((( element custom algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("scale modeling algorithm") OR ((("element custom algorithm") OR ("element method algorithm"))))*.
