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)
"protein coding algorithm" » "protein cosine algorithm" (Expand Search), "protein modeling algorithm" (Expand Search), "protein finding algorithm" (Expand Search), "protein binding algorithm" (Expand Search)
"element data algorithms" » "element art algorithms" (Expand Search), "element all algorithms" (Expand Search), "element both algorithms" (Expand Search), "settlement data algorithms" (Expand Search), "relevant data algorithms" (Expand Search), "movement 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 processing algorithm") OR ("protein coding algorithm"))) OR ("element data algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image processing algorithm\") OR (\"protein coding algorithm\"))) OR (\"element data algorithms\"))".
• Removing quotes may allow a broader search: (((( image processing algorithm ) OR ( protein coding algorithm ))) OR ( element data algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("image processing algorithm") OR ("protein coding algorithm"))) OR ("element data algorithms"))*.
