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)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"recent data algorithms" » "recent art algorithms" (Expand Search), "recent all algorithms" (Expand Search), "recent both algorithms" (Expand Search), "relevant data 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: (("recent data algorithms") OR ((("elemental mapping algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"recent data algorithms\") OR (((\"elemental mapping algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( recent data algorithms ) OR ((( elemental mapping algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("recent data algorithms") OR ((("elemental mapping algorithm") OR ("neural coding algorithm"))))*.
