Perhaps you should try some spelling variations:
"path modeling algorithm" » "path scheduling algorithm" (Expand Search), "spatial modeling algorithm" (Expand Search)
"elements method algorithm" » "elements mould algorithm" (Expand Search)
"data relating algorithm" » "data regulating algorithm" (Expand Search), "data relations algorithm" (Expand Search), "data relative 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: (("elements method algorithm") OR ((("data relating algorithm") OR ("path modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements method algorithm\") OR (((\"data relating algorithm\") OR (\"path modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( elements method algorithm ) OR ((( data relating algorithm ) OR ( path modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements method algorithm") OR ((("data relating algorithm") OR ("path modeling algorithm"))))*.
