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)
"bathssssh algorithm" » "bathhssssh algorithm" (Expand Search), "batshssssh algorithm" (Expand Search), "bhathssssh algorithm" (Expand Search), "bathssssh algoritmo" (Expand Search)
"bathsshhsshssh algorithm" » "bathhsshhsshssh algorithm" (Expand Search), "batshsshhsshssh algorithm" (Expand Search), "bhathsshhsshssh algorithm" (Expand Search), "bathsshhsshssh 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 (((\"bathssssh algorithm\") OR (\"bathsshhsshssh algorithm\"))))~".
• Removing quotes may allow a broader search: (( bat algorithm ) OR ((( bathssssh algorithm ) OR ( bathsshhsshssh algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("bat algorithm") OR ((("bathssssh algorithm") OR ("bathsshhsshssh algorithm"))))*.
