Perhaps you should try some spelling variations:
"case modeling algorithm" » "case making algorithm" (Expand Search), "based modeling algorithm" (Expand Search), "data modeling algorithm" (Expand Search), "a modeling algorithm" (Expand Search)
"image routing algorithm" » "image finding algorithm" (Expand Search), "image making algorithm" (Expand Search), "image clustering algorithm" (Expand Search), "image 1_using algorithm" (Expand Search), "image 2_using algorithm" (Expand Search), "image 3_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 ((("image routing algorithm") OR ("case modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"image routing algorithm\") OR (\"case modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( image routing algorithm ) OR ( case modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("image routing algorithm") OR ("case modeling algorithm"))))*.
