Perhaps you should try some spelling variations:
"case matching algorithms" » "case matching algorithm" (Expand Search), "case pacing algorithms" (Expand Search), "case making algorithm" (Expand Search), "score matching algorithms" (Expand Search), "closely matching algorithms" (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 method algorithm") OR ("element cscap algorithm"))) OR ("case matching algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element method algorithm\") OR (\"element cscap algorithm\"))) OR (\"case matching algorithms\"))".
• Removing quotes may allow a broader search: (((( element method algorithm ) OR ( element cscap algorithm ))) OR ( case matching algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("element method algorithm") OR ("element cscap algorithm"))) OR ("case matching algorithms"))*.
