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)
"source coding algorithm" » "source cosine algorithm" (Expand Search), "source modeling algorithm" (Expand Search), "source finding algorithm" (Expand Search), "source code algorithm" (Expand Search), "source codes algorithm" (Expand Search)
"element cscap algorithm" » "element cc3d algorithm" (Expand Search), "element ipca algorithm" (Expand Search), "element custom 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 cscap algorithm") OR ("element method algorithm"))) OR ("source coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element cscap algorithm\") OR (\"element method algorithm\"))) OR (\"source coding algorithm\"))".
• Removing quotes may allow a broader search: (((( element cscap algorithm ) OR ( element method algorithm ))) OR ( source coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element cscap algorithm") OR ("element method algorithm"))) OR ("source coding algorithm"))*.
