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)
"bathsssshsssh algorithm" » "bathhsssshsssh algorithm" (Expand Search), "batshsssshsssh algorithm" (Expand Search), "bhathsssshsssh algorithm" (Expand Search), "bathsssshsssh algoritmo" (Expand Search)
"bathsssshsshsshssh algorithm" » "bathhsssshsshsshssh algorithm" (Expand Search), "batshsssshsshsshssh algorithm" (Expand Search), "bhathsssshsshsshssh algorithm" (Expand Search), "bathsssshsshsshssh 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 (((\"bathsssshsssh algorithm\") OR (\"bathsssshsshsshssh algorithm\"))))~".
• Removing quotes may allow a broader search: (( bat algorithm ) OR ((( bathsssshsssh algorithm ) OR ( bathsssshsshsshssh algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("bat algorithm") OR ((("bathsssshsssh algorithm") OR ("bathsssshsshsshssh algorithm"))))*.
