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