Perhaps you should try some spelling variations:
"element making algorithm" » "element learning algorithm" (Expand Search), "element finding algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling algorithm" (Expand Search)
"element cnn algorithm" » "element mean algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search)
"data modeling algorithm" » "data modelling algorithm" (Expand Search), "data models 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 making algorithm") OR ("element cnn algorithm"))) OR ("data modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element making algorithm\") OR (\"element cnn algorithm\"))) OR (\"data modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( element making algorithm ) OR ( element cnn algorithm ))) OR ( data modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element making algorithm") OR ("element cnn algorithm"))) OR ("data modeling algorithm"))*.
