Perhaps you should try some spelling variations:
"data modelling algorithm" » "data scheduling algorithm" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"data present algorithm" » "net present algorithm" (Expand Search), "past present algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("data present algorithm") OR ("data modelling algorithm"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data present algorithm\") OR (\"data modelling algorithm\"))) OR (\"element method algorithm\"))*".
• Removing quotes may allow a broader search: (((( data present algorithm ) OR ( data modelling algorithm ))) OR ( element method algorithm ))*.
