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