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)
"data routing algorithm" » "data finding algorithm" (Expand Search), "data making algorithm" (Expand Search), "data clustering algorithm" (Expand Search), "data groupings algorithm" (Expand Search), "data relating algorithm" (Expand Search), "data using algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search), "elements method 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 method algorithm") OR ((("data routing algorithm") OR ("image modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"data routing algorithm\") OR (\"image modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( data routing algorithm ) OR ( image modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("data routing algorithm") OR ("image modeling algorithm"))))*.
