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)
"element method algorithms" » "element two algorithms" (Expand Search), "element both algorithms" (Expand Search), "element other 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 routing algorithm") OR ("case modeling algorithm"))) OR ("element method algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data routing algorithm\") OR (\"case modeling algorithm\"))) OR (\"element method algorithms\"))".
• Removing quotes may allow a broader search: (((( data routing algorithm ) OR ( case modeling algorithm ))) OR ( element method algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("data routing algorithm") OR ("case modeling algorithm"))) OR ("element method algorithms"))*.
