Perhaps you should try some spelling variations:
"image processing algorithm" » "image routing algorithm" (Expand Search), "image tracking algorithm" (Expand Search), "image boosting algorithm" (Expand Search)
"cfd modeling algorithm" » "cfd making algorithm" (Expand Search), "3d modeling algorithm" (Expand Search), "cox modeling algorithm" (Expand Search), "afm modeling algorithm" (Expand Search)
"element method algorithms" » "element two algorithms" (Expand Search), "element both algorithms" (Expand Search), "element other algorithms" (Expand Search), "elements method algorithms" (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: (("element method algorithms") OR ((("image processing algorithm") OR ("cfd modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithms\") OR (((\"image processing algorithm\") OR (\"cfd modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( element method algorithms ) OR ((( image processing algorithm ) OR ( cfd modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithms") OR ((("image processing algorithm") OR ("cfd modeling algorithm"))))*.
