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