Perhaps you should try some spelling variations:
"fragment based algorithms" » "fragment based algorithm" (Expand Search), "agent based algorithms" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"element both algorithms" » "element art algorithms" (Expand Search), "element four algorithms" (Expand Search), "element box algorithm" (Expand Search), "element data algorithms" (Expand Search), "element te algorithms" (Expand Search), "element mesh 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: (("fragment based algorithms") OR ((("element both algorithms") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"fragment based algorithms\") OR (((\"element both algorithms\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( fragment based algorithms ) OR ((( element both algorithms ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("fragment based algorithms") OR ((("element both algorithms") OR ("neural coding algorithm"))))*.
