Perhaps you should try some spelling variations:
"end routing algorithm" » "end modeling algorithm" (Expand Search), "end finding algorithm" (Expand Search), "end making algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data fusion algorithm" (Expand Search), "data making algorithm" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas 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 ("end routing algorithm"))) OR ("relevant data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data using algorithm\") OR (\"end routing algorithm\"))) OR (\"relevant data algorithm\"))".
• Removing quotes may allow a broader search: (((( data using algorithm ) OR ( end routing algorithm ))) OR ( relevant data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data using algorithm") OR ("end routing algorithm"))) OR ("relevant data algorithm"))*.
