Perhaps you should try some spelling variations:
"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)
"fluent finding algorithm" » "recent finding 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 ("fluent finding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"fragment based algorithm\") OR (\"settlement data algorithm\"))) OR (\"fluent finding algorithm\"))".
• Removing quotes may allow a broader search: (((( fragment based algorithm ) OR ( settlement data algorithm ))) OR ( fluent finding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("fragment based algorithm") OR ("settlement data algorithm"))) OR ("fluent finding algorithm"))*.
