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