Perhaps you should try some spelling variations:
"path modeling algorithm" » "path scheduling algorithm" (Expand Search), "spatial modeling algorithm" (Expand Search)
"element mould algorithm" » "elements mould algorithm" (Expand Search), "element could algorithm" (Expand Search), "element would algorithm" (Expand Search), "element mold algorithm" (Expand Search)
"means clustering algorithm" » "mean 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 mould algorithm") OR ((("means clustering algorithm") OR ("path modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element mould algorithm\") OR (((\"means clustering algorithm\") OR (\"path modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( element mould algorithm ) OR ((( means clustering algorithm ) OR ( path modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element mould algorithm") OR ((("means clustering algorithm") OR ("path modeling algorithm"))))*.
