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