Perhaps you should try some spelling variations:
"case modeling algorithm" » "case making algorithm" (Expand Search), "based modeling algorithm" (Expand Search), "data modeling algorithm" (Expand Search), "a modeling 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)
"elements method algorithm" » "elements network algorithm" (Expand Search), "elements means algorithm" (Expand Search), "elements mean algorithm" (Expand Search), "element method 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: (("elements method algorithm") OR ((("case modeling algorithm") OR ("data routing algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements method algorithm\") OR (((\"case modeling algorithm\") OR (\"data routing algorithm\"))))".
• Removing quotes may allow a broader search: (( elements method algorithm ) OR ((( case modeling algorithm ) OR ( data routing algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements method algorithm") OR ((("case modeling algorithm") OR ("data routing algorithm"))))*.
