Perhaps you should try some spelling variations:
"elements matching algorithm" » "elements making algorithm" (Expand Search), "elements modeling algorithm" (Expand Search), "elements mining algorithm" (Expand Search), "elements within algorithm" (Expand Search), "element mapping algorithm" (Expand Search)
"test using algorithms" » "test pacing algorithms" (Expand Search), "test nine algorithms" (Expand Search), "test sorting algorithms" (Expand Search), "tests using algorithms" (Expand Search), "tested using algorithms" (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 matching algorithm") OR ((("test using algorithms") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements matching algorithm\") OR (((\"test using algorithms\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( elements matching algorithm ) OR ((( test using algorithms ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements matching algorithm") OR ((("test using algorithms") OR ("neural coding algorithm"))))*.
