Perhaps you should try some spelling variations:
"data training algorithms" » "data learning algorithms" (Expand Search), "data learning algorithm" (Expand Search), "data tracking algorithms" (Expand Search), "data pertaining algorithms" (Expand Search), "data mining algorithms" (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)
"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 ((("data training algorithms") OR ("case modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements method algorithm\") OR (((\"data training algorithms\") OR (\"case modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( elements method algorithm ) OR ((( data training algorithms ) OR ( case modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements method algorithm") OR ((("data training algorithms") OR ("case modeling algorithm"))))*.
