Perhaps you should try some spelling variations:
"flow modeling algorithm" » "flow making algorithm" (Expand Search), "low modeling algorithm" (Expand Search)
"element method algorithms" » "element two algorithms" (Expand Search), "element both algorithms" (Expand Search), "element other algorithms" (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)

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 update algorithm") OR ("element method algorithms"))) OR ("flow modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element update algorithm\") OR (\"element method algorithms\"))) OR (\"flow modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( element update algorithm ) OR ( element method algorithms ))) OR ( flow modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element update algorithm") OR ("element method algorithms"))) OR ("flow modeling algorithm"))*.
