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)
"bathsshsshsshsshssh algorithm" » "bathhsshsshsshsshssh algorithm" (Expand Search), "batshsshsshsshsshssh algorithm" (Expand Search), "bhathsshsshsshsshssh algorithm" (Expand Search), "bathsshsshsshsshssh algoritmo" (Expand Search)
"bhatsshsssh algorithm" » "bhatsshsssh 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 (((\"bhatsshsssh algorithm\") OR (\"bathsshsshsshsshssh algorithm\"))))~".
• Removing quotes may allow a broader search: (( bat algorithm ) OR ((( bhatsshsssh algorithm ) OR ( bathsshsshsshsshssh algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("bat algorithm") OR ((("bhatsshsssh algorithm") OR ("bathsshsshsshsshssh algorithm"))))*.
