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