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