Perhaps you should try some spelling variations:
"post routing algorithm" » "post modeling algorithm" (Expand Search), "post finding algorithm" (Expand Search), "post making algorithm" (Expand Search), "post docking algorithm" (Expand Search), "post dosing 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)

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