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