Perhaps you should try some spelling variations:
"element mapping algorithm" » "element making algorithm" (Expand Search), "element mining algorithm" (Expand Search), "element learning algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "argument mapping algorithm" (Expand Search)
"element cnn algorithm" » "element mean algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search)
"element gnb algorithm" » "element mnb algorithm" (Expand Search), "element anbs algorithm" (Expand Search), "element b algorithm" (Expand Search), "element g algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("element cnn algorithm") OR ("element gnb algorithm"))) OR ("element mapping algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element cnn algorithm\") OR (\"element gnb algorithm\"))) OR (\"element mapping algorithm\"))".
• Removing quotes may allow a broader search: (((( element cnn algorithm ) OR ( element gnb algorithm ))) OR ( element mapping algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element cnn algorithm") OR ("element gnb algorithm"))) OR ("element mapping algorithm"))*.
