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