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)
"bathsshsssh algorithm" » "bathhsshsssh algorithm" (Expand Search), "batshsshsssh algorithm" (Expand Search), "bhathsshsssh algorithm" (Expand Search), "bathsshsssh algoritmo" (Expand Search)
"batsshsshshsshsshssh algorithm" » "bathsshsshshsshsshssh algorithm" (Expand Search), "batssshsshshsshsshssh algorithm" (Expand Search), "bhatsshsshshsshsshssh algorithm" (Expand Search), "batsshsshshsshsshssh 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 (((\"bathsshsssh algorithm\") OR (\"batsshsshshsshsshssh algorithm\"))))~".
• Removing quotes may allow a broader search: (( bat algorithm ) OR ((( bathsshsssh algorithm ) OR ( batsshsshshsshsshssh algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("bat algorithm") OR ((("bathsshsssh algorithm") OR ("batsshsshshsshsshssh algorithm"))))*.
