Perhaps you should try some spelling variations:
"derived using algorithms" » "derived pacing algorithms" (Expand Search), "derived nine algorithms" (Expand Search), "derived sorting algorithms" (Expand Search), "derived routing algorithms" (Expand Search), "derived fusion algorithms" (Expand Search), "derived making algorithms" (Expand Search)
"data using algorithm" » "data routing algorithm" (Expand Search), "data fusion algorithm" (Expand Search), "data making algorithm" (Expand Search)
"element based algorithm" » "engagement based 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 based algorithm") OR ((("data using algorithm") OR ("derived using algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element based algorithm\") OR (((\"data using algorithm\") OR (\"derived using algorithms\"))))".
• Removing quotes may allow a broader search: (( element based algorithm ) OR ((( data using algorithm ) OR ( derived using algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("element based algorithm") OR ((("data using algorithm") OR ("derived using algorithms"))))*.
