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