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)
"relevant data algorithms" » "relevant art algorithms" (Expand Search), "relevant all algorithms" (Expand Search), "relevant both algorithms" (Expand Search)
"element cscap algorithm" » "element cc3d algorithm" (Expand Search), "element ipca algorithm" (Expand Search), "element custom 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 ((("relevant data algorithms") OR ("element cscap algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"light processing algorithm\") OR (((\"relevant data algorithms\") OR (\"element cscap algorithm\"))))".
• Removing quotes may allow a broader search: (( light processing algorithm ) OR ((( relevant data algorithms ) OR ( element cscap algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("light processing algorithm") OR ((("relevant data algorithms") OR ("element cscap algorithm"))))*.
