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