Perhaps you should try some spelling variations:
"bat algorithm" » "bath algorithm" (Expand Search), "bats algorithm" (Expand Search), "bhat algorithm" (Expand Search), "bat algoritmo" (Expand Search)
"bathhsshsshsssh algorithm" » "bathhhsshsshsssh algorithm" (Expand Search), "batshhsshsshsssh algorithm" (Expand Search), "bhathhsshsshsssh algorithm" (Expand Search), "bathhsshsshsssh algoritmo" (Expand Search)
"bhatsssssshsshssh algorithm" » "bhatsssssshsshssh algoritmo" (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 (((\"bathhsshsshsssh algorithm\") OR (\"bhatsssssshsshssh algorithm\"))))~".
• Removing quotes may allow a broader search: (( bat algorithm ) OR ((( bathhsshsshsssh algorithm ) OR ( bhatsssssshsshssh algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("bat algorithm") OR ((("bathhsshsshsssh algorithm") OR ("bhatsssssshsshssh algorithm"))))*.
