Perhaps you should try some spelling variations:
"reverse learning algorithm" » "reverse learning algorithms" (Expand Search), "remote learning algorithm" (Expand Search)
"client sampling algorithm" » "client making algorithm" (Expand Search), "client modeling algorithm" (Expand Search), "client mining 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: (((("reverse learning algorithm") OR ("recent class algorithm"))) OR ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"reverse learning algorithm\") OR (\"recent class algorithm\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( reverse learning algorithm ) OR ( recent class algorithm ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("reverse learning algorithm") OR ("recent class algorithm"))) OR ("client sampling algorithm"))*.
