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)
"system sorting algorithms" » "system routing algorithm" (Expand Search), "system learning algorithms" (Expand Search), "system during algorithms" (Expand Search), "waste sorting algorithms" (Expand Search), "system strings algorithms" (Expand Search)
"element data algorithm" » "element data algorithms" (Expand Search), "element update algorithm" (Expand Search), "element atlas algorithm" (Expand Search), "settlement data algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement data 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: (("element data algorithm") OR ((("image processing algorithm") OR ("system sorting algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element data algorithm\") OR (((\"image processing algorithm\") OR (\"system sorting algorithms\"))))".
• Removing quotes may allow a broader search: (( element data algorithm ) OR ((( image processing algorithm ) OR ( system sorting algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("element data algorithm") OR ((("image processing algorithm") OR ("system sorting algorithms"))))*.
