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 mesh algorithm" » "element best algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element means algorithm" (Expand Search), "element method algorithm" (Expand Search), "elements mges algorithm" (Expand Search), "element te algorithm" (Expand Search)
"elements wt algorithms" » "elements art algorithms" (Expand Search), "elements two algorithms" (Expand Search), "elements ml algorithms" (Expand Search), "elements _ algorithms" (Expand Search), "elements b algorithms" (Expand Search), "elements fe algorithms" (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 modeling algorithm") OR ((("element mesh algorithm") OR ("elements wt algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data modeling algorithm\") OR (((\"element mesh algorithm\") OR (\"elements wt algorithms\"))))".
• Removing quotes may allow a broader search: (( data modeling algorithm ) OR ((( element mesh algorithm ) OR ( elements wt algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("data modeling algorithm") OR ((("element mesh algorithm") OR ("elements wt algorithms"))))*.
