Perhaps you should try some spelling variations:
"states algorithm" » "search algorithm" (Expand Search)
"error algorithm" » "entropy algorithm" (Expand Search), "search algorithm" (Expand Search)
"bath algorithm" » "search algorithm" (Expand Search), "batsh algorithm" (Expand Search), "bhath algorithm" (Expand Search)
"bat algorithm" » "bats algorithm" (Expand Search), "bhat algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"bat algorithm\") OR (\"bath algorithm\"))) OR (\"states algorithm\"))) OR (\"error algorithm\"))~".
• Removing quotes may allow a broader search: (((((( bat algorithm ) OR ( bath algorithm ))) OR ( states algorithm ))) OR ( error algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((((("bat algorithm") OR ("bath algorithm"))) OR ("states algorithm"))) OR ("error algorithm"))*.
