Perhaps you should try some spelling variations:
"data modeling algorithm" » "data scheduling algorithm" (Expand Search), "data models algorithm" (Expand Search), "spatial modeling algorithm" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search)
"elements ices algorithms" » "elements ies algorithms" (Expand Search), "elements ces algorithms" (Expand Search), "elements ines 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 ((("elements ices algorithms") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data modeling algorithm\") OR (((\"elements ices algorithms\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( data modeling algorithm ) OR ((( elements ices algorithms ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data modeling algorithm") OR ((("elements ices algorithms") OR ("element method algorithm"))))*.
