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)
"fold modeling algorithm" » "fold making algorithm" (Expand Search), "field modeling algorithm" (Expand Search), "flood modeling algorithm" (Expand Search), "yield modeling algorithm" (Expand Search)
"element data algorithms" » "element art algorithms" (Expand Search), "element all algorithms" (Expand Search), "element both algorithms" (Expand Search), "settlement data algorithms" (Expand Search), "relevant data algorithms" (Expand Search), "movement data 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 data algorithms") OR ((("image processing algorithm") OR ("fold modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element data algorithms\") OR (((\"image processing algorithm\") OR (\"fold modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( element data algorithms ) OR ((( image processing algorithm ) OR ( fold modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element data algorithms") OR ((("image processing algorithm") OR ("fold modeling algorithm"))))*.
