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