Perhaps you should try some spelling variations:
"data processing algorithm" » "data routing algorithm" (Expand Search), "data tracking algorithm" (Expand Search), "data boosting algorithm" (Expand Search), "image processing algorithm" (Expand Search)
"case modeling algorithm" » "case making algorithm" (Expand Search), "based modeling algorithm" (Expand Search), "data modeling algorithm" (Expand Search), "a modeling algorithm" (Expand Search)
"element tree algorithms" » "element three algorithms" (Expand Search), "element art algorithms" (Expand Search), "element two algorithms" (Expand Search), "element ree algorithms" (Expand Search), "element te algorithms" (Expand Search), "element ore 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: (("element tree algorithms") OR ((("data processing algorithm") OR ("case modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element tree algorithms\") OR (((\"data processing algorithm\") OR (\"case modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( element tree algorithms ) OR ((( data processing algorithm ) OR ( case modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element tree algorithms") OR ((("data processing algorithm") OR ("case modeling algorithm"))))*.
