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)
"batssssh algorithm" » "bathssssh algorithm" (Expand Search), "batsssssh algorithm" (Expand Search), "bhatssssh algorithm" (Expand Search), "batssssh algoritmo" (Expand Search)
"bathsshhhsshsshsshhsshssh algorithm" » "bathhsshhhsshsshsshhsshssh algorithm" (Expand Search), "batshsshhhsshsshsshhsshssh algorithm" (Expand Search), "bhathsshhhsshsshsshhsshssh algorithm" (Expand Search), "bathsshhhsshsshsshhsshssh 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 (((\"batssssh algorithm\") OR (\"bathsshhhsshsshsshhsshssh algorithm\"))))~".
• Removing quotes may allow a broader search: (( bat algorithm ) OR ((( batssssh algorithm ) OR ( bathsshhhsshsshsshhsshssh algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("bat algorithm") OR ((("batssssh algorithm") OR ("bathsshhhsshsshsshhsshssh algorithm"))))*.
