Perhaps you should try some spelling variations:
"element mapping algorithm" » "element making algorithm" (Expand Search), "element learning algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "argument mapping algorithm" (Expand Search)
"recent mining algorithm" » "recent finding algorithm" (Expand Search), "recent making algorithm" (Expand Search), "recent training algorithms" (Expand Search), "recent findings algorithm" (Expand Search)
"recent class algorithm" » "recent lasso algorithm" (Expand Search), "recent pass algorithm" (Expand Search), "recent means algorithm" (Expand Search), "recent years algorithm" (Expand Search), "latent class algorithm" (Expand Search), "recent past 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: (((("recent mining algorithm") OR ("recent class algorithm"))) OR ("element mapping algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"recent mining algorithm\") OR (\"recent class algorithm\"))) OR (\"element mapping algorithm\"))".
• Removing quotes may allow a broader search: (((( recent mining algorithm ) OR ( recent class algorithm ))) OR ( element mapping algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("recent mining algorithm") OR ("recent class algorithm"))) OR ("element mapping algorithm"))*.
