Perhaps you should try some spelling variations:
"light processing algorithm" » "signal processing algorithm" (Expand Search), "post processing algorithm" (Expand Search), "time processing algorithm" (Expand Search)
"present novel algorithm" » "present forest algorithm" (Expand Search), "present model algorithm" (Expand Search)
"elements over algorithm" » "elements other algorithms" (Expand Search), "elements new algorithm" (Expand Search), "elements em algorithm" (Expand Search), "elements under algorithm" (Expand Search), "events over algorithm" (Expand Search), "elements ree 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: (("light processing algorithm") OR ((("present novel algorithm") OR ("elements over algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"light processing algorithm\") OR (((\"present novel algorithm\") OR (\"elements over algorithm\"))))".
• Removing quotes may allow a broader search: (( light processing algorithm ) OR ((( present novel algorithm ) OR ( elements over algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("light processing algorithm") OR ((("present novel algorithm") OR ("elements over algorithm"))))*.
