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