Perhaps you should try some spelling variations:
"image 2_using algorithm" » "image routing algorithm" (Expand Search), "image using algorithms" (Expand Search), "image twisting algorithm" (Expand Search), "image 1_using algorithm" (Expand Search), "image 2_single algorithm" (Expand Search), "image 2_long algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"presence data algorithms" » "presence art algorithms" (Expand Search), "presence all algorithms" (Expand Search), "presence both algorithms" (Expand Search), "prevalence 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: (("image 2_using algorithm") OR ((("element method algorithm") OR ("presence data algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image 2_using algorithm\") OR (((\"element method algorithm\") OR (\"presence data algorithms\"))))".
• Removing quotes may allow a broader search: (( image 2_using algorithm ) OR ((( element method algorithm ) OR ( presence data algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("image 2_using algorithm") OR ((("element method algorithm") OR ("presence data algorithms"))))*.
