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