Perhaps you should try some spelling variations:
"based modeling algorithm" » "based making algorithm" (Expand Search), "based model algorithm" (Expand Search), "based models algorithm" (Expand Search)
"element network algorithm" » "element new algorithm" (Expand Search), "alignment network algorithm" (Expand Search)
"data backing algorithm" » "data tracking algorithm" (Expand Search), "data making algorithm" (Expand Search), "data tracking 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: (("element network algorithm") OR ((("data backing algorithm") OR ("based modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element network algorithm\") OR (((\"data backing algorithm\") OR (\"based modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( element network algorithm ) OR ((( data backing algorithm ) OR ( based modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element network algorithm") OR ((("data backing algorithm") OR ("based modeling algorithm"))))*.
