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