Perhaps you should try some spelling variations:
"data represent algorithm" » "data present algorithm" (Expand Search), "data presented algorithm" (Expand Search), "data regression algorithm" (Expand Search), "dots represent algorithm" (Expand Search), "may represent algorithm" (Expand Search), "bars represent algorithm" (Expand Search)
"data modeling algorithm" » "data making algorithm" (Expand Search), "data modelling algorithm" (Expand Search), "data models algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean 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: (((("data represent algorithm") OR ("data modeling algorithm"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data represent algorithm\") OR (\"data modeling algorithm\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( data represent algorithm ) OR ( data modeling algorithm ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data represent algorithm") OR ("data modeling algorithm"))) OR ("element method algorithm"))*.
