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)
"element network algorithm" » "element new algorithm" (Expand Search), "alignment network algorithm" (Expand Search)
"elements ppm algorithm" » "elements ppo algorithm" (Expand Search), "elements pso algorithm" (Expand Search), "elements em algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "elements b algorithm" (Expand Search), "elements fe 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 ppm algorithm") OR ("element network algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image processing algorithm\") OR (((\"elements ppm algorithm\") OR (\"element network algorithm\"))))".
• Removing quotes may allow a broader search: (( image processing algorithm ) OR ((( elements ppm algorithm ) OR ( element network algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("image processing algorithm") OR ((("elements ppm algorithm") OR ("element network algorithm"))))*.
