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)
"elements small algorithms" » "elements all algorithms" (Expand Search), "elements ml algorithms" (Expand Search), "elements slam algorithms" (Expand Search)
"element mesh algorithm" » "element best algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element means algorithm" (Expand Search), "element method algorithm" (Expand Search), "elements mges algorithm" (Expand Search), "element te 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 ((("element mesh algorithm") OR ("elements small algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image processing algorithm\") OR (((\"element mesh algorithm\") OR (\"elements small algorithms\"))))".
• Removing quotes may allow a broader search: (( image processing algorithm ) OR ((( element mesh algorithm ) OR ( elements small algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("image processing algorithm") OR ((("element mesh algorithm") OR ("elements small algorithms"))))*.
