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