Perhaps you should try some spelling variations:
"element training algorithms" » "element learning algorithms" (Expand Search), "element learning algorithm" (Expand Search), "lenet training algorithms" (Expand Search), "experiment training algorithms" (Expand Search), "movements training algorithms" (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)
"element rf algorithm" » "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element art algorithms" (Expand Search), "element ore algorithm" (Expand Search), "element ree 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 rf algorithm") OR ((("element training algorithms") OR ("level coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element rf algorithm\") OR (((\"element training algorithms\") OR (\"level coding algorithm\"))))".
• Removing quotes may allow a broader search: (( element rf algorithm ) OR ((( element training algorithms ) OR ( level coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element rf algorithm") OR ((("element training algorithms") OR ("level coding algorithm"))))*.
