Perhaps you should try some spelling variations:
"spine modeling algorithm" » "spine making algorithm" (Expand Search), "space modeling algorithm" (Expand Search), "joint modeling algorithm" (Expand Search), "panel modeling algorithm" (Expand Search)
"element update algorithm" » "element pass algorithm" (Expand Search), "element data algorithms" (Expand Search), "element ipca algorithm" (Expand Search), "element data algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion 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 using algorithm") OR ("spine modeling algorithm"))) OR ("element update algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data using algorithm\") OR (\"spine modeling algorithm\"))) OR (\"element update algorithm\"))".
• Removing quotes may allow a broader search: (((( data using algorithm ) OR ( spine modeling algorithm ))) OR ( element update algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data using algorithm") OR ("spine modeling algorithm"))) OR ("element update algorithm"))*.
