Perhaps you should try some spelling variations:
"cloud modeling algorithm" » "cloud making algorithm" (Expand Search), "flood modeling algorithm" (Expand Search), "cloud model algorithm" (Expand Search), "flow 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)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean 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: (("cloud modeling algorithm") OR ((("element update algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"cloud modeling algorithm\") OR (((\"element update algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( cloud modeling algorithm ) OR ((( element update algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("cloud modeling algorithm") OR ((("element update algorithm") OR ("element method algorithm"))))*.
