Perhaps you should try some spelling variations:
"ann modeling algorithm" » "ann making algorithm" (Expand Search), "a modeling algorithm" (Expand Search), "afm modeling algorithm" (Expand Search), "data modeling algorithm" (Expand Search)
"element data algorithms" » "element art algorithms" (Expand Search), "element all algorithms" (Expand Search), "element both algorithms" (Expand Search), "settlement data algorithms" (Expand Search), "relevant data algorithms" (Expand Search), "movement data algorithms" (Expand Search)
"fragment based algorithm" » "agent based 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: (("element data algorithms") OR ((("ann modeling algorithm") OR ("fragment based algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element data algorithms\") OR (((\"ann modeling algorithm\") OR (\"fragment based algorithm\"))))".
• Removing quotes may allow a broader search: (( element data algorithms ) OR ((( ann modeling algorithm ) OR ( fragment based algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element data algorithms") OR ((("ann modeling algorithm") OR ("fragment based algorithm"))))*.
