Perhaps you should try some spelling variations:
"image processing algorithm" » "image modeling algorithm" (Expand Search), "image routing algorithm" (Expand Search), "image tracking algorithm" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas algorithm" (Expand Search)
"elements rf algorithm" » "elements _ algorithm" (Expand Search), "elements ii algorithm" (Expand Search), "elements art algorithms" (Expand Search), "elements ree algorithm" (Expand Search), "elements res 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: (("image processing algorithm") OR ((("elements rf algorithm") OR ("relevant data algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image processing algorithm\") OR (((\"elements rf algorithm\") OR (\"relevant data algorithm\"))))".
• Removing quotes may allow a broader search: (( image processing algorithm ) OR ((( elements rf algorithm ) OR ( relevant data algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("image processing algorithm") OR ((("elements rf algorithm") OR ("relevant data algorithm"))))*.
