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 cscap algorithm" » "element cc3d algorithm" (Expand Search), "element ipca algorithm" (Expand Search), "element custom algorithm" (Expand Search)
"element best algorithm" » "element forest algorithm" (Expand Search), "element based algorithm" (Expand Search), "element new algorithm" (Expand Search), "element mesh algorithm" (Expand Search), "element te algorithm" (Expand Search), "element fbe 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 cscap algorithm") OR ("element best algorithm"))) OR ("image 1_using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element cscap algorithm\") OR (\"element best algorithm\"))) OR (\"image 1_using algorithm\"))".
• Removing quotes may allow a broader search: (((( element cscap algorithm ) OR ( element best algorithm ))) OR ( image 1_using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element cscap algorithm") OR ("element best algorithm"))) OR ("image 1_using algorithm"))*.
