Perhaps you should try some spelling variations:
"test matching algorithm" » "test making algorithm" (Expand Search), "test modeling algorithm" (Expand Search), "test mining algorithm" (Expand Search), "case matching algorithm" (Expand Search), "thus matching algorithm" (Expand Search), "interest matching algorithm" (Expand Search)
"elements method algorithm" » "elements network algorithm" (Expand Search), "elements means algorithm" (Expand Search), "elements mean algorithm" (Expand Search), "element method algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding 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: (((("elements method algorithm") OR ("test matching algorithm"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements method algorithm\") OR (\"test matching algorithm\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( elements method algorithm ) OR ( test matching algorithm ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements method algorithm") OR ("test matching algorithm"))) OR ("neural coding algorithm"))*.
