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)
"presence data algorithms" » "presence art algorithms" (Expand Search), "presence all algorithms" (Expand Search), "presence both algorithms" (Expand Search), "presence update algorithms" (Expand Search), "presence atlas algorithms" (Expand Search), "presence each algorithms" (Expand Search), "prevalence data algorithms" (Expand Search)
"element data algorithm" » "element update algorithm" (Expand Search), "element atlas algorithm" (Expand Search), "element each algorithm" (Expand Search), "settlement data algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement data 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 data algorithm") OR ("presence data algorithms"))) OR ("data modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element data algorithm\") OR (\"presence data algorithms\"))) OR (\"data modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( element data algorithm ) OR ( presence data algorithms ))) OR ( data modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element data algorithm") OR ("presence data algorithms"))) OR ("data modeling algorithm"))*.
