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 three algorithms" » "element forest algorithms" (Expand Search), "element based algorithms" (Expand Search), "element art algorithms" (Expand Search), "element ree algorithms" (Expand Search), "element te algorithms" (Expand Search), "element ore algorithms" (Expand Search)
"elements res algorithm" » "elements best algorithm" (Expand Search), "elements rast algorithm" (Expand Search), "elements new algorithm" (Expand Search), "elements ree algorithm" (Expand Search), "elements mges algorithm" (Expand Search), "elements ices 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 modeling algorithm") OR ((("elements res algorithm") OR ("element three algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data modeling algorithm\") OR (((\"elements res algorithm\") OR (\"element three algorithms\"))))".
• Removing quotes may allow a broader search: (( data modeling algorithm ) OR ((( elements res algorithm ) OR ( element three algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("data modeling algorithm") OR ((("elements res algorithm") OR ("element three algorithms"))))*.
