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)
"presence data algorithms" » "presence art algorithms" (Expand Search), "presence all algorithms" (Expand Search), "presence both algorithms" (Expand Search), "presence update algorithms" (Expand Search), "presence atlas algorithms" (Expand Search), "presence each algorithms" (Expand Search), "prevalence data algorithms" (Expand Search)
"recent data algorithm" » "recent update algorithm" (Expand Search), "recent atlas algorithm" (Expand Search), "recent each algorithm" (Expand Search), "relevant 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: (("image processing algorithm") OR ((("recent data algorithm") OR ("presence data algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image processing algorithm\") OR (((\"recent data algorithm\") OR (\"presence data algorithms\"))))".
• Removing quotes may allow a broader search: (( image processing algorithm ) OR ((( recent data algorithm ) OR ( presence data algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("image processing algorithm") OR ((("recent data algorithm") OR ("presence data algorithms"))))*.
