Perhaps you should try some spelling variations:
"light processing algorithm" » "light modeling algorithm" (Expand Search), "light routing algorithm" (Expand Search), "light tracking algorithm" (Expand Search), "signal processing algorithm" (Expand Search), "time processing algorithm" (Expand Search)
"elements based algorithm" » "experiments based algorithm" (Expand Search), "elements related algorithm" (Expand Search)
"element ore algorithm" » "element rf algorithm" (Expand Search), "element rl algorithm" (Expand Search), "element erf algorithm" (Expand Search), "element te algorithm" (Expand Search), "element fbe algorithm" (Expand Search), "element 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 ((("elements based algorithm") OR ("element ore algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"light processing algorithm\") OR (((\"elements based algorithm\") OR (\"element ore algorithm\"))))".
• Removing quotes may allow a broader search: (( light processing algorithm ) OR ((( elements based algorithm ) OR ( element ore algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("light processing algorithm") OR ((("elements based algorithm") OR ("element ore algorithm"))))*.
