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