Perhaps you should try some spelling variations:
"tests using algorithms" » "tests pacing algorithms" (Expand Search), "tests nine algorithms" (Expand Search), "tests sorting algorithms" (Expand Search), "tested using algorithms" (Expand Search), "results using algorithms" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"elements tree algorithms" » "elements three algorithms" (Expand Search), "elements art algorithms" (Expand Search), "elements two algorithms" (Expand Search), "elements ree algorithms" (Expand Search), "element ree algorithms" (Expand Search), "elements res 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: (((("elements tree algorithms") OR ("tests using algorithms"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements tree algorithms\") OR (\"tests using algorithms\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( elements tree algorithms ) OR ( tests using algorithms ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements tree algorithms") OR ("tests using algorithms"))) OR ("neural coding algorithm"))*.
