Perhaps you should try some spelling variations:
"current sampling algorithm" » "current making algorithm" (Expand Search), "current modeling algorithm" (Expand Search), "current mining algorithm" (Expand Search), "current smoking algorithm" (Expand Search), "client sampling 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)
"level coding algorithm" » "level cosine algorithm" (Expand Search), "level modeling algorithm" (Expand Search), "level finding algorithm" (Expand Search), "level according algorithm" (Expand Search), "level using 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 ((("current sampling algorithm") OR ("level coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element update algorithm\") OR (((\"current sampling algorithm\") OR (\"level coding algorithm\"))))".
• Removing quotes may allow a broader search: (( element update algorithm ) OR ((( current sampling algorithm ) OR ( level coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element update algorithm") OR ((("current sampling algorithm") OR ("level coding algorithm"))))*.
