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)
"bathsssh algorithm" » "bathhsssh algorithm" (Expand Search), "batshsssh algorithm" (Expand Search), "bhathsssh algorithm" (Expand Search), "bathsssh algoritmo" (Expand Search)
"bathhsshhhsshsshsshsshssh algorithm" » "bathhhsshhhsshsshsshsshssh algorithm" (Expand Search), "batshhsshhhsshsshsshsshssh algorithm" (Expand Search), "bhathhsshhhsshsshsshsshssh algorithm" (Expand Search), "bathhsshhhsshsshsshsshssh 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 (((\"bathsssh algorithm\") OR (\"bathhsshhhsshsshsshsshssh algorithm\"))))~".
• Removing quotes may allow a broader search: (( bat algorithm ) OR ((( bathsssh algorithm ) OR ( bathhsshhhsshsshsshsshssh algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("bat algorithm") OR ((("bathsssh algorithm") OR ("bathhsshhhsshsshsshsshssh algorithm"))))*.
