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