Perhaps you should try some spelling variations:
"improvements using algorithms" » "movements using algorithms" (Expand Search), "improvement among algorithms" (Expand Search), "improvements can algorithms" (Expand Search), "improvements pacing algorithms" (Expand Search), "improvements nine algorithms" (Expand Search), "improvements sorting algorithms" (Expand Search)
"data fitting algorithm" » "data finding algorithm" (Expand Search), "data filtering algorithm" (Expand Search), "data twisting algorithm" (Expand Search), "data settings algorithm" (Expand Search), "data mining algorithm" (Expand Search)
"element data algorithm" » "element data algorithms" (Expand Search), "element update algorithm" (Expand Search), "element atlas algorithm" (Expand Search), "settlement data algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement data 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: (((("improvements using algorithms") OR ("element data algorithm"))) OR ("data fitting algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"improvements using algorithms\") OR (\"element data algorithm\"))) OR (\"data fitting algorithm\"))".
• Removing quotes may allow a broader search: (((( improvements using algorithms ) OR ( element data algorithm ))) OR ( data fitting algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("improvements using algorithms") OR ("element data algorithm"))) OR ("data fitting algorithm"))*.
