Perhaps you should try some spelling variations:
"bhatssh algorithm" » "bat algorithm" (Expand Search), "states algorithm" (Expand Search)
"error algorithm" » "entropy algorithm" (Expand Search), "search algorithm" (Expand Search)
"bats algorithm" » "bat algorithm" (Expand Search), "states algorithm" (Expand Search)
"bath algorithm" » "bat algorithm" (Expand Search), "search algorithm" (Expand Search), "states 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: "((((\"bats algorithm\") OR (\"error algorithm\"))) OR (((\"bath algorithm\") OR (\"bhatssh algorithm\"))))~".
• Removing quotes may allow a broader search: (((( bats algorithm ) OR ( error algorithm ))) OR ((( bath algorithm ) OR ( bhatssh algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (((("bats algorithm") OR ("error algorithm"))) OR ((("bath algorithm") OR ("bhatssh algorithm"))))*.
