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)
"tests using algorithms" » "tests pacing algorithms" (Expand Search), "tests nine algorithms" (Expand Search), "tests sorting algorithms" (Expand Search), "tested using algorithms" (Expand Search), "results using algorithms" (Expand Search)
"element data algorithm" » "element data algorithms" (Expand Search), "element update algorithm" (Expand Search), "element atlas algorithm" (Expand Search), "settlement data algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement data 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 data algorithm") OR ("tests using algorithms"))) OR ("image processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element data algorithm\") OR (\"tests using algorithms\"))) OR (\"image processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element data algorithm ) OR ( tests using algorithms ))) OR ( image processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element data algorithm") OR ("tests using algorithms"))) OR ("image processing algorithm"))*.
