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