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