Perhaps you should try some spelling variations:
"visual routing algorithm" » "visual modeling algorithm" (Expand Search), "visual finding algorithm" (Expand Search), "visual making algorithm" (Expand Search), "visual grounding algorithm" (Expand Search), "visual working algorithm" (Expand Search), "visual growing algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data fusion algorithm" (Expand Search), "data making algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("visual routing algorithm") OR ("data using algorithm"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"visual routing algorithm\") OR (\"data using algorithm\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( visual routing algorithm ) OR ( data using algorithm ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("visual routing algorithm") OR ("data using algorithm"))) OR ("element method algorithm"))*.
