Perhaps you should try some spelling variations:
"engagement based algorithm" » "management based algorithm" (Expand Search), "fragment based algorithm" (Expand Search), "engagement model algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion algorithm" (Expand Search)
"solved using algorithm" » "solved using algorithms" (Expand Search), "solved routing algorithm" (Expand Search), "solved fusion 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 ("solved using algorithm"))) OR ("engagement based algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data using algorithm\") OR (\"solved using algorithm\"))) OR (\"engagement based algorithm\"))".
• Removing quotes may allow a broader search: (((( data using algorithm ) OR ( solved using algorithm ))) OR ( engagement based algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data using algorithm") OR ("solved using algorithm"))) OR ("engagement based algorithm"))*.
