Perhaps you should try some spelling variations:
"implement modeling algorithm" » "element modeling algorithm" (Expand Search), "element modelling algorithm" (Expand Search), "implement making 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)
"element abs algorithm" » "element anbs algorithm" (Expand Search), "element pass algorithm" (Expand Search), "element b algorithm" (Expand Search), "element fbe algorithm" (Expand Search), "element data algorithm" (Expand Search), "element mesh 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: (((("element abs algorithm") OR ("element update algorithm"))) OR ("implement modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element abs algorithm\") OR (\"element update algorithm\"))) OR (\"implement modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( element abs algorithm ) OR ( element update algorithm ))) OR ( implement modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element abs algorithm") OR ("element update algorithm"))) OR ("implement modeling algorithm"))*.
