Perhaps you should try some spelling variations:
"elements custom algorithm" » "elements control algorithm" (Expand Search), "elements auction algorithm" (Expand Search), "elements cosine algorithm" (Expand Search)
"data using algorithms" » "data cosine algorithm" (Expand Search)
"experiments based algorithm" » "experimental 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: (((("experiments based algorithm") OR ("elements custom algorithm"))) OR ("data using algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"experiments based algorithm\") OR (\"elements custom algorithm\"))) OR (\"data using algorithms\"))".
• Removing quotes may allow a broader search: (((( experiments based algorithm ) OR ( elements custom algorithm ))) OR ( data using algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("experiments based algorithm") OR ("elements custom algorithm"))) OR ("data using algorithms"))*.
