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)
"bathhhsshsssh algorithm" » "bathhhhsshsssh algorithm" (Expand Search), "batshhhsshsssh algorithm" (Expand Search), "bhathhhsshsssh algorithm" (Expand Search), "bathhhsshsssh algoritmo" (Expand Search)
"batsshsshsshsshssh algorithm" » "bathsshsshsshsshssh algorithm" (Expand Search), "batssshsshsshsshssh algorithm" (Expand Search), "bhatsshsshsshsshssh algorithm" (Expand Search), "batsshsshsshsshssh 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 (((\"bathhhsshsssh algorithm\") OR (\"batsshsshsshsshssh algorithm\"))))~".
• Removing quotes may allow a broader search: (( bat algorithm ) OR ((( bathhhsshsssh algorithm ) OR ( batsshsshsshsshssh algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("bat algorithm") OR ((("bathhhsshsssh algorithm") OR ("batsshsshsshsshssh algorithm"))))*.
