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 method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"post clustering algorithm" » "host clustering algorithm" (Expand Search), "novo clustering algorithm" (Expand Search), "som clustering 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 method algorithm") OR ((("post clustering algorithm") OR ("ann modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"post clustering algorithm\") OR (\"ann modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( post clustering algorithm ) OR ( ann modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("post clustering algorithm") OR ("ann modeling algorithm"))))*.
