Perhaps you should try some spelling variations:
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion algorithm" (Expand Search)
"settlement data algorithms" » "settlement art algorithms" (Expand Search), "settlement all algorithms" (Expand Search), "settlement both algorithms" (Expand Search)
"gmm clustering algorithm" » "_ clustering 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 ("gmm clustering algorithm"))) OR ("settlement data algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data using algorithm\") OR (\"gmm clustering algorithm\"))) OR (\"settlement data algorithms\"))".
• Removing quotes may allow a broader search: (((( data using algorithm ) OR ( gmm clustering algorithm ))) OR ( settlement data algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("data using algorithm") OR ("gmm clustering algorithm"))) OR ("settlement data algorithms"))*.
