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)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas algorithm" (Expand Search)
"data finding algorithm" » "path finding algorithm" (Expand Search), "data fitting algorithm" (Expand Search), "case finding 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 1_using algorithm") OR ("data finding algorithm"))) OR ("relevant data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image 1_using algorithm\") OR (\"data finding algorithm\"))) OR (\"relevant data algorithm\"))".
• Removing quotes may allow a broader search: (((( image 1_using algorithm ) OR ( data finding algorithm ))) OR ( relevant data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("image 1_using algorithm") OR ("data finding algorithm"))) OR ("relevant data algorithm"))*.
