Perhaps you should try some spelling variations:
"image modeling algorithm" » "image making algorithm" (Expand Search), "age modeling algorithm" (Expand Search), "climate modeling algorithm" (Expand Search), "case modeling algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"present data algorithms" » "present art algorithms" (Expand Search), "present all algorithms" (Expand Search), "present both algorithms" (Expand Search), "presence data algorithms" (Expand Search), "present day algorithms" (Expand Search), "recent 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 modeling algorithm") OR ((("element method algorithm") OR ("present data algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image modeling algorithm\") OR (((\"element method algorithm\") OR (\"present data algorithms\"))))".
• Removing quotes may allow a broader search: (( image modeling algorithm ) OR ((( element method algorithm ) OR ( present data algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("image modeling algorithm") OR ((("element method algorithm") OR ("present data algorithms"))))*.
